An airflow passage is formed between an outer surface of the hammer case and the cover and is configured so as to allow inflow and outflow of outside air. The cover is held so as to be slightly movable by sandwiching an elastic member in an axial line direction and, by the cover being moving forward and backward during its operation, air goes into or comes out of the airflow passage to cool the hammer case.
The present invention improves durability. A work machine includes a support section, an impact section movably supported by the support section and moving from a non-impact position to an impact position on one side in a first direction to perform an impact operation of exerting an impact force on an impacted member, and a lubricant feeding section feeding a lubricant to the impact section in response to the impact operation of the impact section.
A working tool includes a magazine unit in which a plurality of connected fasteners are stored in a rolled shape, an ejection unit to which the fastener is fed, a driver blade configured to strike the fastener held in the ejection unit to one side in a first direction, an electric motor configured to drive the driver blade by receiving an electric power, a feeder unit capable of moving in a second direction crossing the first direction and configured to feed the fastener stored in the magazine unit to the ejection unit by moving to one side in the second direction, a solenoid configured to drive the feeder unit by receiving an electric power, and a control unit configured to allow the solenoid to drive when a load of the electric motor satisfies a first condition.
Provided is a work machine capable of estimating position information of a brushless motor from a current, even when an operation unit is in an off state. A control unit 41 transitions from constant speed control to deceleration control when a switch 5 is turned off at a time t14. The deceleration control is for decreasing a duty ratio to a prescribed value (for example, 10%) and decreasing a rotor rotational speed at a smaller deceleration than inertial rotation. The control unit 41 performs the deceleration control when the rotor rotational speed exceeds a prescribed rotational speed. The control unit 41 detects (estimates) the rotor position on the basis of the motor current even when performing deceleration control, and transitions from the deceleration control to acceleration control when the switch 5 is turned on during the deceleration control.

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.
