Abstract: A wheel bearing device has a vehicle-body-mounting flange 5b with a plurality of ears 10 discontinuously formed in a circumferential direction on an outer circumferential surface of the outer member 5. An outer circumferential surface 11 on the outer side of the outer member is tapered and formed such that a diameter of the outer member gradually decreases in a direction to an outer side. Ridges 16 protrude from a fitting surface 12 toward the outside in a radial direction. The ridges 16 are formed between the plurality of ears 10. The ridges 16 are forged to smoothly connect to the outer circumferential surfaces of the plurality of ears 10. Ribs 15 are forged on inner-side outer circumferential surfaces of the plurality of ears 10.

Abstract: A wheel bearing apparatus has an outer member, an inner member and double row rolling elements contained between outer raceway surfaces and inner raceway surfaces, respectively, of the outer member and the inner member. A vibration damping mechanism is mounted on a portion of the outer member or the inner member except at portions engaging with mating components.
