Abstract
A bearing device () for a vehicle wheel provided with: an outer member (); and an inner member comprising a hub wheel (), and at least one inner wheel () press-fitted into the small-diameter ridge (A) of the hub wheel (); wherein a belt-shaped part (F) that radially protrudes by a protrusion amount (P) is formed over a prescribed width (W) in the outer peripheral surface of the outer member () so that at least part of the belt-shaped part (F) radially overlaps the outside rolling surface (D) which is on the vehicle-wheel-attachment-flange-facing side of the outer member (). The present invention addresses the problem of providing a bearing device for a vehicle wheel in which the amount of deformation in an opening of an outer member can be reduced and decreases in rolling fatigue service life can be prevented while keeping overall weight increase to a minimum.
