<p>PROBLEM TO BE SOLVED: To prevent occurrence of a judder when applying the brakes by enhancing profile irregularity of the mounting surface 28 of a mounting flange provided on a hub 8, relative to the rotation axis of the hub 8. SOLUTION: A protruding part 27 is provided on an opposite surface to a mounting surface 28, which is a part of a mounting flange 13, so as to surround the opening part of a mounting hole 23 to press-in and fix a stud 24. Thereby, deformation caused by pressing-in the stud 24 in the mounting hole 23 does not reach the mounting surface 28, and occurrence of a judder can be prevented when applying the brakes. Otherwise, the mounting surface 28 is finished after pressing-in and fixing the stud 24.</p> |
