Abstract

PURPOSE:To eliminate the leakage of a pressure medium by a method wherein an air bag is arranged in the cylinder and a piston is moved by the contraction and expansion of the air bag. CONSTITUTION:The air bag 17 having an opening 18 faced toward the outside of the cylinder 11 is provided in the cylinder 11. The opening 18 is pinched by a pinching member 19 having a ventilating port 20 for the pressure medium. The piston 14, provided in the cylinder 11, is energized toward the inside of the cylinder 11 by a coil spring 21.
