マスターシリンダ。[Claims for Utility Model Registration] (1) A casing, a piston that is provided to be slidable in the axial direction within the casing and defines a hydraulic chamber, and a casing and a piston that are slidable on the inner peripheral surface of the piston. A master cylinder is provided with a cup seal that is provided between the cup seal and seals the hydraulic chamber when the piston moves in one direction, and that can introduce reserve oil into the hydraulic chamber when the piston moves in the other direction. A master cylinder characterized in that an annular base portion and a lip portion are provided on the circumferential surface of the piston and are spaced apart from each other in the axial direction of the piston and protrude inward. (2) A communication hole is formed in the piston to allow communication between the inside of the reservoir tank and the hydraulic chamber, and when the communication hole is closed by the base portion, the hydraulic chamber is sealed. The master cylinder according to claim 1.
