Abstract
A bearing device for a wheel is capable of suppressing a backlash in a circumferential direction, is excellent in coupling operability of a hub wheel and an outer joint member of a constant velocity universal joint, and is excellent for maintenance by allowing separation of the hub wheel and the outer joint member of the constant velocity universal joint. In the bearing device for a wheel, a hub wheel, and a shaft section of the outer joint member of a constant velocity universal joint are separably coupled with each other through a recess-projection fitting structure, the shaft section being inserted in a fitting manner into a hole portion of the hub wheel. Projecting portions extending in an axial direction are provided on one of an outer surface of the shaft section of the outer joint member and an inner surface of the hole portion of the hub wheel.
