    摘要： The wheel drive motor according to the invention includes a motor shaft (35) having a large diameter portion (35d) located at a central part in the axial direction and a small diameter portion (35b) located on a first side in the axial direction, a bearing (36b) rotatably supporting the small diameter portion (35b), and a rotor (24) secured to an outer circumferential surface (35j) of the large diameter portion (35d). An end part (24p) of the rotor (24) located on the first side in the axial direction projects over an end face (35e) of the large diameter portion (35d) located on the first side in the axial direction toward the side on which the small diameter portion (35b) is.
