A joint assembly has a pair of constant velocity universal joints and a connecting drive shaft. A cover unit protects the constant velocity universal joints and prevents hanging down of the joints under their own weight. The unit cover is arranged to cover the outer circumferential surfaces of the pair of constant velocity universal joints and boots. The unit cover is formed from elastomer material by injection molding. The cover unit inner circumferential surface has a configuration corresponding to the outline configurations of the pair of constant velocity universal joints and the boots.

An axle module with a bearing apparatus has an outer joint member 14 axially secured relative to a wheel hub 1 by a caulked portion 13. The caulked portion 12 is formed by plastically deforming the end portion of a shaft portion 20 of the outer joint member 14 onto the end face 12 of the wheel hub 1. A pitch circle diameter PCDi of the inner side ball group is larger than a pitch circle diameter PCDo of the outer side ball group. The size of all the balls 6a, 6b is the same. The number of balls 6b of the inner side ball group is set larger than the number of balls 6a of the outer side ball group.

A wheel bearing apparatus for a driving wheel is formed as a unit of a wheel hub, a double row rolling bearing and a constant velocity universal joint. The double row rolling bearing has an outer member with a body mounting flange mounted on a knuckle and double row outer raceway surfaces. An inner member includes the wheel hub and an outer joint member of the constant velocity universal joint. The wheel hub has an inner raceway surface corresponding to one of the double row outer raceway surfaces. The outer joint member has another inner raceway surface corresponding to the other of the double row outer raceway surfaces. Double row rolling elements are rollably arranged between the outer and inner raceway surfaces. Seals are mounted in an annular space opening formed between the outer member and the inner member. A sensor is fit into a mounting aperture formed in the knuckle. A pulser ring is mounted on the outer circumferential surface of the outer joint member. It opposes the sensor via a predetermined radial gap. The outer diameter of the pulser ring is smaller than the inner diameter of the knuckle.

A bearing device for a wheel prevents backlash in a circumferential direction and has excellent workability for connecting a hub wheel and an outer joint member of a constant velocity universal joint. The bearing device includes a recess-projection fitting structure in which the hub wheel and a shaft section, which is fitted in a hole of the hub wheel of the outer joint member of the constant velocity universal joint, are unitized together. In the recess-projection fitting structure, entire fitting regions among projections on the outer surface of the shaft section of the outer joint member and recesses, which fit on the projections, are brought into intimate contact with each other.

Provided is a bearing device for a wheel that can realize prevention of a backlash in a circumferential direction and is excellent in workability of connection of a hub wheel and an outer joint member of a constant velocity universal joint. Further, provided is a bearing device for a wheel that can prevent deterioration in NVH characteristics, which is caused by the backlash occurring in a joint section between the hub wheel and the constant velocity universal joint or between an outer member and a knuckle, and can perform rotation torque transmission with high accuracy. The bearing device includes a recess-projection fitting structure (M) in which the hub wheel (1) and a shaft section (12), which is fitted in a hole (22) of the hub wheel (1) of the outer joint member of the constant velocity universal joint (3) are unitized together. In the recess-projection fitting structure (M), entire fitting regions among projections (35) on the outer surface of the shaft section (12) of the outer joint member and recesses (36), which fit on the projections, are brought into intimate contact with each other.
