Abstract
A wheel support apparatus including a hub wheel which includes a hub shaft and is to mount a wheel thereon, a first side surface spline being formed on an end surface of the hub shaft, and a constant velocity joint which includes an outer ring connected to the hub shaft in a torque-transmitting manner, a second side surface spline meshed with the first side surface spline being formed on an end surface of a side wall portion of the outer ring abutting against the end surface of the hub shaft. Each of the first and second side surface splines includes a number of spline teeth and bottom lands defined between the spline teeth. The tooth tops of the spline teeth of one of the two side splines and the bottom lands of the other side spline are formed into a tapering surface inclined relative to a plane perpendicular to a center axis of the hub shaft. The tapering tooth tops contact the corresponding tapering bottom lands so that the hub shaft and the outer ring can be aligned with each other.
