Abstract

PURPOSE: To prevent causing of nicks on plastic piston while being engaged by catching from both sides a flange through engaging clicks of a disk provided on a diaphragm retaining plate with hooks of a ring provided on a flange of a power piston.
CONSTITUTION: Disk 3 is fixed to diaphragm retaining plate 20 by being caught between plate 20 and the rear portion of flange 1a of power piston 1. Disk 3 has several clicks 3a raised around its circumference. The front portion of flange 1a is fitted with ring 2 having several hooks 2b around its circumference. Ring 2 is fitted with notchs 6 and several projection 2a at seveal positions in radial direction. Hooks 2b of ring 2 engage with clicks 3a of disk 3. Clicks 3a, placed between projections 2a, catch flange portion 1a between them.
