Abstract
A motor-driven wheel includes a wheel disc, a wheel hub, a decelerator, a knuckle, a hub bearing, a constant-velocity joint, an in-wheel motor, and a spring. Since the decelerator is placed closer to the outside of the vehicle relative to the hub bearing, the space where the in-wheel motor is to be mounted can readily be secured. Further, balls are arranged along a spherical external surface of an outer race and the outer race is supported swingably in the axial direction. Thus, even when a great axial force is exerted, the axial force can be endured. The outer race can be supported swingably and rotatably with respect to the wheel hub.
