Abstract
A bearing device for a wheel includes a bearing. The bearing includes outer and inner members and double-row rolling elements. The bearing has a constant velocity universal joint coupled thereto in a torque transmittable manner by fitting a stem section of an outer joint member to a shaft hole of a hub wheel, in which the stem section of the outer joint member is press-fitted to the shaft hole of the hub wheel, and shapes of only the circumferential side wall portions of each of a plurality of convex portions are transferred to the shaft hole, to thereby define a convex and concave fitting portion in which close contact is achieved at an entire contact portion between the plurality of convex portions and the plurality of concave portions.
