PURPOSE:To prevent adhesion of iron dust due to friction with a disc brake and to improve thermal radiation performance. CONSTITUTION:A disc plate 2 is provided independently at the inside of an aluminum wheel 1. Projections and recesses 3 are formed on said disc plate 2 in order to radiate heat being transmitted from a disc 5. With such arrangement, adhesion of iron dust being produced through sliding friction between the disc section 5 of a disc brake and a wheel cylinder 6 can be prevented and thermal radiation performance can be improved. |
