Abstract:
The present invention addresses the problem of providing a bearing device for wheels, the bearing device for wheels being configured so as to reduce an amount of deformation of an opening of an outer member while minimizing an increase of an overall the weight, thus preventing a deterioration in rolling fatigue life. A bearing device for wheels is provided with: an outer member having double-row outer rolling surfaces; a hub ring having a wheel mounting flange and having a small-diameter stepped section; and an inner member constituted by at least one inner ring press-fitted over the small-diameter stepped section, the inner member having double-row inner rolling surfaces facing the double-row outer rolling surfaces. A band-shaped section having a predetermined band width and protruding radially by a protrusion amount is formed on at least a part of the wheel mounting flange-side outer peripheral portion of the opening of the outer member.

Claim (Index 5):
A bearing device for wheels comprising:\n an outer member having a vehicle body mounting flange integrally along an outer periphery, and a multi-row outer rolling surface along an inner periphery; an inner member having a hub ring and at least one inner race, the hub ring having a wheel mounting flange for attachment to a wheel integrally at one end and a small-diameter stepped portion extending axially around an outer periphery, the at least one inner race being press-fitted into the small-diameter stepped portion, the outer periphery being provided with a multi-row inner rolling surface facing the multi-row outer rolling surface; and multi-row rolling elements disposed in a rollable manner between the multi-row inner rolling surface and the multi-row outer rolling surface, wherein a belt-like portion having a predetermined width and extending in a radial direction is provided for at least a part of an outer peripheral portion of an opening of the outer member on a side of the wheel mounting flange.
