Claims

[Scope of utility model registration request]

A cylinder body having a cylinder hole with an open end; a piston that is slidably inserted into the cylinder hole and forms a liquid chamber between the closed end of the cylinder hole; an elongated groove extending in the piston; a through hole provided in the hydraulic pressure chamber side portion of the piston and communicating the elongated hole with the liquid chamber; a valve device capable of blocking liquid movement from the hydraulic pressure chamber to the through hole; a shaft member attached to the cylinder body and having one end fitted into the elongated hole; and a shaft member movably fitted into the through hole and configured to prevent the valve The piston is provided with a valve driving member whose one end is capable of contacting the shaft member in order to open the valve of the device, and the piston is made of a material containing a synthetic resin material, and the piston is sandwiched between the intermediate portion and the cylinder hole. A mask cylinder having a pair of sliding portions formed on an inner circumferential surface, wherein a third sliding portion relative to the inner circumferential surface of the cylinder hole is formed in the intermediate portion.
