Abstract

PURPOSE: To fix a diaphragm tightly without causing any damage to the diaphragm, by caulking a brass plate at the joining portion of a suction piston and the diaphragm.
CONSTITUTION: The first annular plate 13 and bead portion 11 of diaphragm 10 are fitted to an upper portion of suction piston 2 having a small thickness, in the manner that they are superposed on each other. Further, the second annular plate 14 made of plastic metal and curved upward at its peripheral portion is fitted on bead portion 11. In this state, diaphragm 10 and suction piston 2 are coupled with each other by caulking the upper end of suction piston 2 and thereby fixing the second plate 14 tightly in place. In caulking the portion 15 by pressing plate 14, bead portion 11 is not pressed excessively if the caulking force is increased and dimension B can be kept constand, so that displacement of the intake passage due to rotation of suction piston 2 can be prevented.
