A vehicle wheel bearing apparatus for a driven wheel has an outer member integrally formed with a body mounting flange on its outer circumference. The body mounting flange is adapted to be mounted on a knuckle forming part of a suspension apparatus of the vehicle. The outer member inner circumference includes double row outer raceway surfaces. An inner member includes a wheel hub and at least one inner ring. The wheel hub has a wheel mounting flange formed at one end portion. A cylindrical portion axially extends from the wheel mounting flange. The inner ring is press fit onto the cylindrical portion of the wheel hub. The inner member has a plurality of inner raceway surfaces adapted to be arranged opposite to the plurality of outer raceway surfaces. Double row rolling elements are freely rollably contained, via cages, between the outer raceway surfaces and inner raceway surfaces, respectively, of the outer member and the inner member. Seals are arranged in annular spaces formed between the outer member and the inner member. The knuckle is integrally formed with a disc-shaped bottom. The outer member is adapted to be connected to the knuckle, via bolts, with the body mounting flange abutted against the knuckle. The inner side end of the inner member is covered by the knuckle. |
