PURPOSE:To prevent generation of squealing by interposing a vibration-proof rubber between a disc rotor and a hub. CONSTITUTION:A plurality of mount holes 15 are disposed on one side end surface of a hub 5. A vibration-proof rubber structure 17 is formed by putting and fixing a cylindrical rubber damper 19 on the outer periphery of a shaft 18 by baking and further putting a metallic outer cylinder 20 on the outer periphery thereof. The vibration-proof structures 17 are pressed into the mount holes 15 to be fixed therein. The end of the shaft 18 is projected over one side end surface of the hub 5, and provided with a flange portion 21 of a large diameter midway in the projecting portion thereof. The end portion beyond the flange portion 21 is a screw portion 22 passing through a fitting hole 16 of a disc rotor 10. Accordingly, the disc rotor 10 is brought into collision with one side surface of the hub 5 at its central part to insert the screw portion into the fitting hole 16 and is fastened by a nut 23 to press the central portion against the flange portion 21 so as to be fixed on the hub 5. |
