PROBLEM TO BE SOLVED: To provide a compact motor-driven wheel capable of enhancing the ride comfort of a vehicle and enhancing the assemblability and the reliability. SOLUTION: The motor-driven wheel 1 includes a wheel disk 10, a wheel hub 100b, a reduction gear 20, a knuckle 50, a hub bearing 40, a constant velocity joint 30, an in-wheel motor IWM, and a spring 52. Since the reduction gear 20 is arranged on the outer side of the vehicle with respect to the hub bearing 40, the mounting space of the in-wheel motor IWM is easily ensured. An outer race 35 is supported in a rocking manner in the axial direction by balls 36-39 arranged along the spherical outer surface of the outer race 35, the force in the axial direction can be received even when a large force in the axial direction is applied, and the outer race 35 can be supported by the wheel hub 100b in a rocking and rotatable manner.
