したことを特徴とするマスタシリンダ。 A piston that is slidably fitted into an inner hole of a cylinder body via a piston cup in a liquid-tight manner and defines a supply chamber that is constantly in communication with a reservoir and a pressure chamber that is always in communication with a hydraulic pressure pipe; and a return spring that biases the
In the master cylinder, the rod in the recess of the piston is brought into contact with a recess formed at one end of the piston by a rod interlocked with a pedal to push and slide the piston to generate hydraulic pressure in the pressure chamber. A master cylinder characterized in that an annular groove or an annular protrusion concentric with the axis of the piston is formed between a contact surface and an open end thereof.
