Claims

[Scope of utility model registration request]

A main body having a cylinder hole formed therein, a piston that is slidably fitted into the cylinder hole to define a hydraulic chamber, and a piston that is connected to the piston via a spring holder placed on the hydraulic pressure chamber side of the piston. The piston includes a return spring that urges the cylinder hole outwardly, and a sealing device provided on the inner periphery of the open end of the cylinder hole, and the piston includes a flange that slides on the inner periphery of the cylinder hole. and a shaft portion integrally formed with the flange portion and slidably penetrating the sealing device and projecting to the outside, the outside diameter of the shaft portion being smaller than the outside diameter of the flange portion. In the mask cylinder according to the present invention, a sliding surface relative to the inner peripheral surface of the cylinder hole is formed on the outer periphery of the spring receiver, and the inner periphery of the spring receiver is integrally connected to the piston.
