のピストンロツク装置。 A lock piston having a ball lock groove in which a number of locking balls are fitted into engagement lock grooves provided on the circumferential surface of a lock rod integrally connected to the piston, and which restricts the outward movement of the balls in the radial direction. In the piston lock device for a fluid pressure cylinder, the lock piston is moved in the axial direction by a spring to restrict the axial movement of the piston, and a ring-shaped engagement groove is provided on the outer peripheral surface of the lock piston. A piston locking device for a fluid pressure cylinder, characterized in that an eccentric protrusion of a lock release pin provided to be rotatably operated from the outside is engaged in the engagement groove.
