According to a first aspect of the present invention, an assembly in which a spring, a valve seat, a nozzle, and a spring holder (container) are integrally assembled is incorporated into a main body, and the spring is a front assembly. Therefore, when assembled into the main body, it does not jump out of the main body, and can be screwed and fixed by an automatic machine. In addition, since the assembly is simply performed by incorporating the assembled holder into the main body, the assembled nozzle can be viewed. Further, the gas introduced from the gas inflow port passes around the holder (container) and is guided into the holder through a hole 18b provided on the back side of the holder, and a valve formed of a valve rubber and a nozzle in the holder. Through the pressure regulating chamber, there is a holder around the valve rubber, which acts as an obstacle to dust and the like, it is difficult for dust to reach the valve rubber, and there are few troubles such as gas leakage.
