The attaching flange (13) is formed with a plurality of circumferentially disposed attaching holes (15). The amount of axial projection (h) by which the peripheral portion of the opening edge of each attaching hole (15) projects from an attaching surface (14) is not more than 10 mum when a stud (9) is force-fitted in the attaching hole (15). This suppresses the runout of a rotor (2) fixed to the attaching surface (14) of the attaching flange (13), thereby suppressing judder that is likely to occur during braking. |
