The spring elements 13, the first 11 and the second piston part 12 are connected to one another in a loss-proof manner, in order to form an integral module 10.

A manufacturing method of a brake disc, comprising the steps of: processing a rotor S1 to acquire the rotor made of the approximately annular plate material with a center hole, the opening edge of said center hole having a plurality of projections projecting inwardly; processing a bracket S2 to acquire a bracket made of a tubular member, in which openings corresponding to the projections are formed; and integrating the bracket S4 with the rotor by inserting the bracket through the center hole of the rotor acquired by the rotor processing step and fitting the projections of the rotor into the openings of the bracket, along with a disc brake acquired according to the manufacturing method of the brake disc.

An outer joint member includes a cutout portion that is formed at least at each corner portion on an opening side of a cup section, which is defined between a radially inner opening end portion of each of track grooves and a radially inner spherical surface portion formed between the track grooves. The cutout portion is configured to prevent a cage from interfering with the outer joint member when the cage is incorporated into the outer joint member. The cutout portion and the track grooves of the outer joint member are finished by cold-forging ironing using a single ironing punch.

A piston manufacturing device includes a first forming device (42) configured to form an annular groove (61) in a piston (11), and a second forming device (52) configured to press an edge (15) of an opening (14) of the piston (11) toward other end side in an axial direction of the piston (11) and to form a thick section (65) extruded from an inner circumferential surface (12b) arranged between the edge (15) and the groove (61) toward an axial center side of the piston (11), wherein a recessed section (53) is formed at a portion of the second forming device (52) that is arranged to abut the edge (15) so that an inner circumferential side of the edge (15) is plastically deformed toward the other end side in an axial direction of the piston (11).
