機構。 A locking mechanism for a fluid pressure cylinder device for locking a sliding cylinder slidably fitted outside a fixed piston of the fluid pressure cylinder device at an end of a moving stroke, the locking mechanism being formed on a peripheral wall of the fixed piston. In addition to placing the sphere in the through hole,
A recess into which the sphere can fit is formed in the inner wall of the sliding cylinder at the stroke end of the sliding cylinder, and the fixed piston is always biased in one direction by a spring and moves up and down. 1. A lock mechanism for a fluid pressure cylinder device, characterized in that a lock piston is provided, the lock piston being able to be held and having a recess formed in its outer periphery into which the sphere can fit.
