The present invention improves workability. In a circular saw 10, a protrusion-amount-adjusting mechanism 60 has a lever-biasing spring 80 that biases a fixing nut 74 and an operation lever 78 toward the distal end of a fixing bolt 70 (i.e., in a direction away from a link 66). Therefore, it is possible to satisfactorily maintain a state in which the fixing nut 74 is positioned at a non-fixed position. Specifically, it is possible to satisfactorily maintain a state in which the fixing nut 74 and the operation lever 78 are separated from the link 66. This makes it possible for the fixing nut 74 and the operation lever 78 to suppress sliding of the link 66 when a circular saw body 30 is caused to rotate relative to a base 20 in a state in which the circular saw body 30 and the base 20 are unfixed from one another. Therefore, it is possible to improve workability in adjusting the amount of protrusion of a circular saw blade 12.

This invention optimally reciprocates a cutting blade. In this motorized cutting machine 10, a control unit 100 detects an initial position and a reversing position on the basis of a detection signal from a lifter detection switch 68, and the rpms of the motor 50. Namely, the motor 50 is drive-controlled by means of the control unit 100 to allow the travel of a lifter 65 and a blade 72 to be halted in the initial position and the reversing position. As a result thereof, for example, without providing a switching mechanism or the like for switching between disconnected and connected states of the path transmitting the motor drive force to the lifter, the lifter 65 can be halted or reversed in the reversing position. Accordingly, the lifter 65 and the blade 72 can be made to travel optimally.
Provided is an easy-to-use portable electrical device. The electrical device 1 has: a grip 4 to be held by a worker; a battery holding part 7 disposed on one end side of the grip 4 and onto which a battery 18 is mounted; and a spotlight 20 and floodlights 21, 22, the irradiation directions of which relative to the grip 4 can be changed.

The present invention suppresses deterioration in work efficiency. An electric cutting machine 10 has a battery mounting portion 28 provided at a rear end portion of a housing 20, and a battery 34 is mounted to the battery mounting portion 28. Now, a cover unit 70 is attached to the battery mounting portion 28 of the housing 20, and a lower cover 71 of the cover unit 70 covers the battery 34 from a lower side. Accordingly, in a case of a worker happening to lift a rear end portion of the electric cutting machine 10, the lower cover 71 is lifted. That is to say, the worker can be suppressed from directly lifting the battery 34. As a result, lifting force can be suppressed from being directly input to the battery 34. Accordingly, deformation and damage of the battery 34 and the battery mounting portion 28 can be suppressed, and work efficiency can be improved.

Provided is a work machine that suppresses the occurrence of operation failures and that realizes an enhancement in performance. This work machine includes a head valve as a cutoff part that switchably connects and cuts off a space on an intake port side and a space on an exhaust port side. The cut off part includes: a base member 26 movable between a cut off position and a connection position; and an annular seal member that contacts a passage cut-off surface to cut off an air passage when the base member 26 is at the cut off position. A fitting groove 61 in which the annular seal member fits is formed on an end of the base member. The fitting groove 61 includes: an inner circumference contact wall 62 that contacts an inner circumference side of the annular seal member; an outer circumference contact wall 63 that contacts an outer circumference side; an inclined surface 67 that contacts the outside in the axial direction of the annular seal member; and a protrusion part 64 that contacts the outside of the annular seal member.
The present invention improves workability. A cutting work machine 10 has a discharge passage 80 disposed at an outer peripheral portion of a saw cover 22. The discharge passage 80 is formed in a recess shape that has formed therein a discharge port 81 opened towards the left side. Formed at a front end of the discharge passage 80 is a discharge/inlet port 83. By way of the discharge/inlet port 83, the saw cover 22 and the discharge passage 80 are connected to each other. Further, a side guide surface 84 that constitutes the right lateral surface of the discharge passage 80 is, when viewed from above, inclined more to the left side at a location closer to the rear side. Here, the rear surface of the discharge passage 80 is formed with a rear guide surface 87, and the rear guide surface 87 is inclined more to the back side at a location closer to the left side. This configuration causes cutting chips flowing towards the rear-end side of the discharge passage 80 along the side guide surface 84 to hit the rear guide surface 87 and changes the discharge direction of the cutting chips to the left side (to the discharge-port 81 side). Accordingly, since the cutting chips are discharged approximately leftward from the discharge port 81, it is possible to improve workability of the cutting work machine 10. 1

The present invention achieves miniaturization. In an impact wrench 10, a speed reduction mechanism 60 includes a carrier part 62 integrally formed at a rear end of a spindle 42, and a planetary gear 66 rotatably supported on the carrier part 62, the planetary gear 66 being engaged with a pinion gear 31A of a motor 30. Moreover, the speed reduction mechanism 60 has a bearing 70 for rotatably supporting the carrier part 62, and the bearing 70 is disposed on a radially outer side of a drive shaft 31 of the motor 30, relative to the planetary gear 66. Therefore, compared to a hypothetical configuration in which the carrier part 62 were rotatably supported by the bearing 70 disposed on the front side or the rear side of the planetary gear 66, it is possible to miniaturize the physique of the speed reduction mechanism 60 in the front-rear direction, and to consequently miniaturize the physique of the impact wrench 10 in the front-rear direction. Thus, the front and back distance between a workpiece and a worker can be shortened.

The present invention improves durability with a simple configuration. In a driving machine 10, a housing 14 is attached to a nose 30 so that the housing cannot rotate relative to the nose. Therefore, if the screw connection between the nose 30 and a cylinder 40 becomes loose, the cylinder 40 relatively rotates toward the other side in the rotation direction relative to the nose 30. At that time, a pressure accumulation container 42 acts so as to fasten the cylinder 40, and the cylinder 40 and the pressure accumulation container 42 attempt to rotate integrally toward the other side in the rotation direction relative to the housing 14. Herein, an engagement pin 71 is provided to the housing 14 and engages with an engagement recess 72 of the pressure accumulation container 42, thereby restricting the rotation of the pressure accumulation container 42. Accordingly, the rotation of the cylinder 40 toward the other side in the rotation direction relative to the nose 30 is restricted, and the joined state between the cylinder 40 and the nose 30 can be suitably maintained. Therefore, in the housing 14, there is no need to prepare a plurality of areas for providing the engagement pin 71.
The present invention prevents blank firing with a simple structure. In a driver machine 10, a blank firing prevention mechanism 100 has a feeder position sensor 105 that detects the prohibition position of a feeder 64 of a magazine 60. When a control unit 20 detects the prohibition position of the feeder 64 on the basis of a detection signal from the feeder position sensor 105, the control unit 20 prohibits driving of a motor 52. Thus it is possible to prevent blank firing of a striking part 44. The feeder position sensor 105 is provided to an emission part 34. Thus it is unnecessary for a wire, which connects the control unit 20 and the feeder position sensor 105, to be extended to the outside of a housing 14, in comparison with a structure in which the feeder position sensor 105 is provided in a magazine case 62 of the magazine 60. It is therefore possible, with a simple structure, to prevent blank firing of a nail N.
Provided is a work machine having good operability. A work machine 1 has a motor 3 and a computation unit 40 capable of controlling the output of the motor 3.

The computation unit 40 has an auto stop function for stopping the motor 3 when a set time has elapsed from the start of striking of an end tool. The set time for the auto stop function in the application mode can be changed through use of the portable terminal 80.

The present invention achieves improvement in heat resistance. A dust collection box 80 is configured to comprise: a box entrance section 84B through which an air flow AR1 (air flow AR2 and air flow AR3) is let into a dust chamber 80A; and a box-side exhaust outlet 84E through which the air flow AR1 in the dust chamber 80A is let out of the dust chamber 80A. The box-side exhaust outlet 84E is disposed behind the box entrance section 84B. The dust collection box 80 also has a case guide section which guides the air flow AR1 introduced into the dust chamber 80A toward the downstream side. Accordingly, the air flow AR1 introduced into the dust chamber 80A is caused to flow downward at a front end of the dust chamber 80A, to flow backward at a lower end of the dust chamber 80A, and to flow upward at a rear end of the dust chamber 80A. In other words, it becomes possible to cause the air flow AR1 to flow almost entirely throughout the dust chamber 80A. With this configuration, it is possible to efficiently cool a resin outer case 82 that constitutes the dust chamber 80A.
