Abstract
A bearing device for wheels is configured so as to reduce an amount of deformation of an opening of an outer member while minimizing an increase in overall weight, thus preventing a deterioration in rolling fatigue life. The 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.
