This vibration actuator is for generating vibration in a plate-like panel such as an operation panel by using an elongation/contraction element such as a piezoelectric element, wherein both ends 2a, 2c of a vibration unit 2, in which a connection member C is integrally connected to the elongation/contraction element A having a limited length, are fixed to the back surface or the front surface of a plate-like panel B. As a result, since it becomes possible to expand, in the longitudinal direction, the width of a plate-like panel B that bends due to elongation/contraction of an elongation/contraction element A, and to expand an amplitude w in a bending direction orthogonal to the longitudinal direction, vibration having prescribed amplitude can be generated within the wide range of the plate-like panel.

A clamping device (10) has a clamp arm (20) pivotably housed inside a body (16), and a locating section (54) for positioning workpieces (W1, W2) is provided on an upper portion of the body (16). The locating section (54) is formed with a slit hole (60) which enables a claw portion (76) of the clamp arm (20) to protrude outside, and is provided inside with a shutter (66) facing the slit hole (60) and being movable. The claw portion (76) of the clamp arm (20) is inserted through a clamp hole (72) of the shutter (66). Then, when the clamp arm (20) moves inside the body (16) in the axial direction and rotates, the shutter (66) moves integrally with the clamp arm (20) in the axial direction to cover the slit hole (60). Thus, the opening portion of the slit hole (60) is suitably covered except that portion occupied by the claw portion (76), so that foreign matter and the like can be prevented from entering the locating section (54) through the slit hole (60).
This compressed fluid discharge control device (10) is provided with a diaphragm valve (40). When an opening/closing operation member (14) is operated, a pilot chamber opening/closing valve (92) opens to open a pilot chamber (52). As a result, pressure within a valve chamber (34) becomes higher than that in the pilot chamber (52), and the diaphragm valve (40) separates from a valve seat (39). Then, compressed fluid previously accumulated in a holding chamber (32) flows into a discharge passage (36) through the valve chamber (34) and is discharged from the discharge opening of the discharge passage (36).

A boosting device (10) is provided with: a drive unit (12) which is driven under the action of energization; and a boosting mechanism (14) which is connected to the drive unit (12) and which boosts and outputs a pressurized fluid. The boosting mechanism (14) comprises: a rotating body (30) which is connected to a drive shaft (24) of a drive source (18) and includes a slope portion (68); and four pistons (32a to 32d) opposing the rotating body (30) and disposed moveably in an axial direction. The pistons (32a to 32d) are sequentially and continuously pushed in the axial direction by means of the slope portion (68) of the rotating body (30), whereby the pressurized fluid is compressed and boosted in a boosting chamber (48). The pressurized fluid that has been boosted in the boosting chamber (48) is discharged out of an output port (64) through a discharge passageway (66a, 66b) when an exhaust check valve (36) is opened.

A fluid circuit (10) for air cylinders is provided with a switching valve (14), an air supply source (16), an exhaust port (18), and a check valve (20). When the switching valve is in a first position, one cylinder chamber (32) is connected with the air supply source, and the other cylinder chamber (34) is connected with the exhaust port. When the switching valve is in a second position, the one cylinder chamber is connected with the other cylinder chamber via the check valve, and the one cylinder chamber is connected with the exhaust port.
