Claims (1)

[Claims for Utility Model Registration] 1. A power cylinder section having a power piston driven by compressed air, a first solenoid valve that supplies compressed air to a pressure chamber of the power cylinder section,
a second solenoid valve for discharging compressed air in the pressure chamber to the outside; a control means for controlling opening and closing of the first and second solenoid valves; and a piston rod connected to the power piston and a clutch lever. The slave cylinder section is provided with a slave cylinder section in which a relay piston interconnecting the push rod is disposed so as to be able to reciprocate, and a fluid chamber that supplies hydraulic fluid to the slave cylinder section. In the device, the control means opens the second electromagnetic valve, and the control means opens the second electromagnetic valve;
When the compressed air in the pressure chamber of the power cylinder section is discharged to the outside and the power piston is moved back, the second electromagnetic valve is closed just before the end of the back movement, and after a predetermined period of time has elapsed, A clutch actuator device characterized in that exhaust gas is gradually controlled by alternately opening and closing the solenoid valve. 2. The clutch actuator according to claim 1, wherein the control means gradually controls the exhaust while alternately opening and closing the second solenoid valve just before the end of the return motion of the power piston. Eta device.
