Abstract
A vehicle wheel bearing apparatus has an outer member with a body mounting flange, an inner member and double row rolling elements freely rollably contained between the inner and outer raceway surfaces of the inner and outer members. The body mounting flange is formed with a plurality of screw apertures. An inner side flange surface of the body mounting flange is formed by machining to have a flat vertical surface relative to a longitudinal axis of a wheel hub. An outer side flange surface of the body mounting flange is formed by forging to have a tapered surface of a predetermined inclined angle. Thus, the thickness of the body mounting flange is gradually reduced radially outward.
