Estimating the term…
A wheel bearing device includes a hub ring, a double-row bearing and a constant velocity universal joint which are unitized together. At least one of double-row inner raceways of the bearing and a wheel mounting flange are formed on a hub ring. The hub ring and a stem portion of a joint outer ring of the constant velocity universal joint are fitted through a torque transmission assembly, wherein a pilot member as a separate element having a wheel guide portion and a brake guide portion is fitted to a side-end portion of the wheel mounting flange of the hub ring, and the hub ring and the pilot member are fixed to the joint outer ring by swaging.
A wheel bearing device comprising a hub ring, a double-row bearing and a constant velocity universal joint, at least the hub ring and the double-row bearing are unitized together, the hub ring and the constant velocity universal joint are fitted through torque transmission means and are joined by means for fastening in an axial direction, wherein clearance in a fit portion of the torque transmission means is prevented by a play prevention member, wherein the play prevention member is disposed entirely within a hollow portion positioned inside of the hub ring and is in contact with an inner surface of the hub ring.
