<p>PURPOSE:To facilitate fixing of spring by making a recess in the end face of a piston and securing a retainer member to one end of the spring then stopping the retainer member in the recess and mounting the spring. CONSTITUTION:A recess 2 is formed by a tapered face 2f, small diameter sections 2a, 2c and a large diameter section 2b in the end face 1a of a piston 1 and a retainer member 5 is secured to one end of a spring 3, then the retainer member 5 is stopped in the recess 2 and the spring 3 is mounted on the piston 1. Consequently, the spring 3 can be fixed by simply stopping the retainer member 5 in the recess 2, resulting in facilitation of fixing.</p> |
