Abstract: An input piston and an input rod of a master cylinder are connected such that a spherical tip portion of the input rod is integrally connected in an axial direction and tiltably connected in a radial direction to a concave portion in a bottom portion of a piston inner hole. A sphere diameter of the spherical tip portion is larger than the maximum diameter of a shaft portion in the input rod. The concave portion of the input piston has a conical bottom portion that receives the spherical tip portion and a cylindrical hole portion that can accommodate the spherical tip portion, and the concave portion is formed in the input piston itself. An opening-side end portion of the cylindrical hole portion is configured to be pressed and molded in the axial direction and an inner radial direction by use of a fixture to retain the spherical tip portion.
