An outer ring shaft portion which is extended integrally from an end face of an outer ring of a constant velocity joint is fittingly inserted into an inside hole in a hub shaft of a wheel hub to which a wheel is attached, so that the wheel hub and the constant velocity joint are coupled to each other. Internal splines and external splines are formed on an inner circumferential surface of the inside hole in the hub shaft and an outer circumferential surface of the outer ring shaft portion in such a manner as to mesh with each other. Side face splines are formed on end face of the hub shaft and an end face of the outer ring of the constant velocity joint. In addition, the wheel hub and the constant velocity joint are connected together in such a manner that torque can be transmitted therebetween by the internal and external splines and the side face splines meshing with each other, respectively. |
