The rotor of a braking apparatus is fitted onto a cylindrical positioning portion 19a, and in this condition, fixed to the hub 8a using bolts which are threaded into the screw holes 11a in the rotating flange 10a, and tightened. As the hub 8a rotates, the runout in the radial direction of the outer peripheral surface 20a of the cylindrical positioning portion 19a is controlled up to 15 mum, to suppress the runout of the vehicle wheel. With this construction, running performance such as riding comfort and diving stability is improved. |
