摘要： 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.
