タシリンダの構造。[Claims for Utility Model Registration] (1) Primary and secondary seal members are fixedly arranged in the cylinder hole in the cylinder body, and the primary piston and secondary piston, which are provided with return ports in the seal members, are slidably provided. In a master cylinder that is assembled to generate two systems of hydraulic pressure, and in which the primary side is fixedly supported by the cylinder body being assembled to the booster, the cylinder hole opening end face of the cylinder body that is the side where the primary piston is installed is , a guide bush on which the sealing member is disposed and a cap member for fixing the guide bush are provided, the cap member is temporarily attached to the booster mounting flange of the cylinder body in the master cylinder alone, and when the master cylinder is assembled to the booster, the flange is fixed. A structure of a master cylinder characterized in that a part of the cap member is held between the booster front shell and the seal member that receives hydraulic pressure and the guide bushing from falling out. (2) As the flange temporary attachment structure of the cap member, the outer peripheral surface of the flange is notched in the axial direction to form a through groove, and a fitting piece bent in a U-shape inward from the outer periphery of the cap is fitted into the through groove. 2. The structure of the master cylinder according to claim 1, wherein the master cylinder is engaged by turning.
