<P>PROBLEM TO BE SOLVED: To provide a wheel bearing device having improved connecting work efficiency between a hub ring and the outside joint member of a constant velocity universal joint and improved maintainability with the hub ring separable from the outside joint member of the constant velocity universal joint, while suppressing rattling in the circumferential direction. <P>SOLUTION: One of a shaft portion 12 of the outside joint member of the constant velocity universal joint and a hole portion 22 of the hub ring 1 has a projection 35 extending in the axial direction. The projection 35 is pressed into the other to form a recess 36, whereby a projection-and-recess fitting structure M is configured where all over the fitting sites between the projection 35 and the recess 36 closely contact each other. A screw hole 50 is provided in the axial center of the shaft portion 12 of the outside joint member along the axial direction. To the screw hole 50, a bolt member 54 is threaded to which thrust to the axial center direction is imparted during separating the hub ring 1 from the shaft portion 12 of the outside joint member, to generate separating force. <P>COPYRIGHT: (C)2010,JPO&INPIT |
