<P>PROBLEM TO BE SOLVED: To sufficiently maintain surface run-out precision of a break rotor by positively eliminating influence of deformation by press-fitting of a stud bolt. <P>SOLUTION: A plurality of groove parts 20 are formed between bolt holes 7 on a brake rotor mounting surface 14 side of a flange 6 along a circumferential direction. After the stud bolt 10 is press-fitted to the bolt hole 7, cutting or grinding is applied to an outer diameter side part, an inner diameter side part more than the bolt hole 7 and a part around the stud bolt 10 of a flat surface of the brake rotor mounting surface 14 side of the flange. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
