ABSTRACT:
A bearing apparatus for a driving wheel of a vehicle has a wheel hub (1), a constant velocity universal joint (3) and a double row rolling bearing (2) assembled as a unit. The wheel hub (1) and the outer joint member (14) of the constant velocity universal joint (3) are fitted to each other. At least one of the inner raceway surface (1a) of the double row rolling bearing (2) is formed on the wheel hub. A hardened irregular portion (5) is formed on the inner circumferential surface of the wheel hub (1). The wheel hub1and the outer joint member (14) are integrally connected via plastic deformation of a fitting portion (17b) of the outer joint member. The hardened irregular portion (5) bites into the surface of the fitting (17b). A connected portion of the wheel hub and outer joint member has a plastic deformed connection mechanism having an axial pull-out proof force more than 160 kN.
