Kind Code:
A1
Abstract:
An attaching flange (13) is formed with a plurality of circumferentially-spaced attaching holes (15). The portions around the open edges of these attaching holes (15) are each formed with a recess (38) over the entire open edge of the attaching hole (15) such that the recess is depressed from the attaching surface (14) and is coaxial with the attaching hole (15). Let D be the inner diameter of the recess (38) and d be the inner diameter of the attaching hole (15), and D=d+(5-40 mm). This arrangement prevents deformation, which attends the pressure fitting of a stud (9) into the attaching hole (15), from reaching the attaching surface (14), thus suppressing deflection of a rotor (2) fixed on the attaching surface (14) of an attaching flange (13), thereby suppressing judder that tends to occur during braking.
