Provided are an electric motor which can employ stator coils each having a large sectional area while providing an increased facing area between the magnets of the rotor and the stator, meet the requirements in terms of the radial and axial dimensions, and improve output; a vehicle power device including such an electric motor; a generator; and a generator-equipped wheel bearing including such a generator. The electric motor (1) is of an outer rotor type. The stator core (4) is divided into an annular part (7) and a plurality of teeth (8), each of the teeth (8) includes a distal end part and a tooth main part, the distal end part having a larger circumferential width than a circumferential width of the tooth main part, and the annular part (7) includes a plurality of fitting grooves in the circumferential direction on an outer peripheral surface thereof, each fitting groove extending in an axial direction and having a sectional shape with a narrowed part on an open side. Each of the teeth (8) includes, at a base end part thereof, a fitting part (8c) having a sectional shape that allows the fitting part to be fitted into a fitting groove, the fitting part inserted into the fitting groove of the annular part (7) in the axial direction to be fitted to the annular part (7) in an undetachable manner in a radial direction, and the fitting part (8c) has a maximum width in the circumferential direction smaller than the circumferential width of the tooth main part.
