[Claims for Utility Model Registration] (1) A locking cylinder hole is formed in the closing member that closes the end of the main cylinder body and communicates with the supply port, and a piston rod is inserted into the locking cylinder hole. The locking piston has a locking piston that is slidably mounted in the radial direction, and a biasing means that biases the locking piston toward the piston rod to engage the distal end side of the locking piston with the piston rod. , a cylinder configured such that the locking piston is slid and disengaged from the piston rod by fluid pressure supplied from the supply port to the locking cylinder hole, and the locking piston is disposed in the closing member. After the engagement between the piston rod and the piston rod is released, the supply port and the main cylinder chamber are communicated through the locking cylinder hole,
A lock cylinder that has a flow path that is closed by a lock piston when engaged. (2) The lock cylinder according to claim 1, wherein the closing member is one or both of a head cover and a rod cover.
