Claims

[Scope of utility model registration request]

coupled to a first piston in a first cylinder;
A shaft that moves back and forth by fluid pressure, a locking member provided on the outer periphery of this shaft so as to be movable in the axial direction, a second piston that is integrated with the locking member, and a second piston that is movable in the axial direction. a stored second cylinder, a means for biasing the second piston to move in the locking direction of the locking member, a shaft advancing fluid path communicating with the first cylinder, and a first and second cylinder. A shaft characterized by comprising a fluid path communicating with the cylinder for releasing the locking member and retracting the shaft, and a parallel fluid path including a check valve and a throttle valve provided in the middle of this retracting fluid path. Feeding locking device.
