Abstract
A wheel bearing device suppresses backlash in the circumferential direction and has excellent workability in connecting a hub wheel and an outer joint component of a constant velocity universal joint. The wheel bearing device has a stem shaft of an outer joint component of a constant velocity universal joint fitted into a hole section of a hub wheel that is integrated with the hub wheel by a projection and recess mating structure. In the projection and recess mating structure, an overall recess mating area of a projection is in close contact with a corresponding recess.
