A wheel bearing device has a vehicle-body-mounting flangewith a plurality of earsdiscontinuously formed in a circumferential direction on an outer circumferential surface of the outer member. An outer circumferential surfaceon 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. Ridgesprotrude from a fitting surfacetoward the outside in a radial direction. The ridgesare formed between the plurality of ears. The ridgesare forged to smoothly connect to the outer circumferential surfaces of the plurality of ears. Ribsare forged on inner-side outer circumferential surfaces of the plurality of ears
