Abstract:
1. A mounting mechanism for a push rod of a master cylinder in which a piston is reciprocally movably provided in a cylinder hole of a cylinder main body having openings at the opposite ends, and the piston is brought into contact by a pushing force of a returning spring with one end of the push rod inserted and mounted from the one end of the cylinder main body, the push rod includes a radially projecting coupling end at the end thereof to be brought into contact with the piston, the mounting mechanism comprising: at the side of the cylinder main body that the push rod is to be mounted, a through groove formed at an end surface of the cylinder main body to have such a shape as to pass the coupling end in an inserting state where the longitudinal axes of the cylinder main body and the push rod are held substantially normal to each other and to prevent the coupling end from coming out in a mounting state where the longitudinal axes of the cylinder main body and the push rod are substantially aligned; and an insertion groove formed in the side surface of the cylinder main body in such a manner as to be continuous with the through groove and adapted for passing a rod portion of the push rod in the inserting state.
