PROBLEM TO BE SOLVED: To lock and unlock a bladder assembly without complicating the structure.SOLUTION: When a piston rod 6 moves upwards in a state that a hub 7 is fitted in a lower clamp ring 14, an upper guide 53 pushes out a lock pin 51 to the lower clamp ring 14 side, by which an end 51b of the lock pin 51 is fitted in a groove 14a, and the hub 7 and the lower clamp ring 14 are locked. Meanwhile, when the piston rod 6 comes down, the upper guide 53 is pushed down by a stepped part 6a to the lower side compared to the lock pin 51, and the end 51b of the lock pin 51 biased to the piston rod 6 side drops out of the groove 14a, by which the lock of the hub 7 with the lower clamp ring 14 unlocks.
