A cylindrical pilot portion P to be fitted to an inner periphery of a wheel (80) is formed at an inner diameter part of a brake rotor (70). A shape of the hub wheel, in particular, the shape thereof on an outboard side is thereby simplified, and thus the hub wheel can be fabricated at low cost by cold forging or the like. An outer joint member (31) of an outboard side constant velocity universal joint (30) and a hub wheel (10) are connected with each other by way of a nut member (90). |
