特徴とするマスタシリンダ。 An inlet port that communicates between the cylinder internal pressure chamber formed by the piston fitted into the cylinder and a communication hole that communicates with the reservoir tank outside the cylinder is arranged near the cylinder end and is operated by a valve mechanism that interlocks with the piston. In a portless master cylinder that is opened and closed by the cylinder, its end surface is in contact with the bottom surface of the cylinder inner hole, a slit is formed in the abutment surface, and a brake is provided from the reservoir tank side to the pressure chamber in the outer peripheral groove. A seat member fitted with a lip-shaped sealing cup that allows liquid inflow is fluid-tightly fitted into the cylinder inner hole, and a center portion of the seat member has a minimum diameter sufficient to communicate the reservoir side and the pressure chamber. A master cylinder characterized in that the inlet port is provided in the axial direction, and the reservoir side and the pressure chamber are communicated through a restriction formed by the inlet port.
