８直径は取付穴の直径と略同径である。Valve devices having diaphragms are used in a variety of applications, such as vacuum motors that control the warming of intake air in automobile air cleaners, and valves that control the flow rate of blow-by gas in the crank chamber. As shown in FIG. 1, in this conventional valve device, the outer peripheral end of a substantially disk-shaped diaphragm 21 made of an elastic material such as synthetic rubber is airtightly sandwiched between a cylindrical cover 22 and a case 23. A retainer 11 is disposed at the center to receive a spring 10, and the diaphragm 21 is held by inserting protrusions 25 into a plurality of mounting holes 24 provided in the cover 22 and the retainer 111. The protrusion 25 consists of a conical top 26 on the base 21 and a neck 28 with an annular groove 27.
The locking portion 29 of the conical seat 6 is slightly larger than the diameter of the mounting hole 24. The width of the annular groove 27 of the neck 28 is <-
22 and the thickness of the retainer 11, the top part 2
8. The diameter is approximately the same as the diameter of the mounting hole.

トが高くなるといった欠点かある。The protruding portion 26 of this conventional diaphragm 21 is connected to the locking portion 2
9 has a larger diameter than the mounting hole 24, it requires a great deal of force and skill to insert and assemble the cover 22 into the mounting hole 24 of the retainer 11 against the resistance of the locking part 29. Productivity is poor because of this, and if it is used with incomplete insertion, airtightness cannot be maintained and performance cannot be achieved. Further, since the protrusion 25 of the diaphragm 21 needs to be sized so that it does not come off the cover 22 and the retainer 11, the dimensional accuracy of the protrusion 25 must be improved, resulting in an increase in manufacturing cost.
