Abstract
A bearing device for a wheel has minimized circumferential play and allows a hub ring and an outer joint member of a constant velocity universal joint to be connected with excellent workability. Axially extending projections are formed on either one of the outer diameter surface of a shaft of the outer joint member and the inner diameter surface of a hole of the hub ring, and the projections are axially press fitted into the other. Recesses fitted in an intimate contact manner onto the projections are formed in the other. Thus, a recess/projection fitting structure is formed. In the structure, the entire fitting/contact portions of the projections and the recesses are in intimate contact with each other. Further, a shaft come-out prevention structure is provided between the shaft of the outer joint member and the inner diameter surface of the hub ring.
