Claims

[Scope of utility model registration request]

A locking mechanism for a fluid pressure cylinder device for locking a piston slidably fitted into a cylinder of the fluid pressure cylinder device at the end of a moving stroke, the locking mechanism comprising a sphere inserted into a through hole formed in a peripheral wall of the piston. At the same time, a recess into which the sphere can fit is formed in the inner wall of the cylinder at the stroke end of the piston, and the 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.
