ABSTRACT:
A wheel motor for a vehicle is provided in which an electric motor is arranged in a central space defined in a wheel, to rotatably drive the wheel. A gear reducer is also arranged in the central space of the wheel, which has a plurality of gears including a final stage gear having an axial through hole formed therein. The electric motor includes a housing fixed to the vehicle body, a stator secured to the housing, a rotor rotatably fitted in a central space defined in the stator to generate the rotative driving force during rotation thereof, and an output shaft connected to the rotor through the gear reducer as well as to the wheel to be rotatively driven by the rotor, for transmitting the rotating output from the rotor through the gear reducer to the wheel. The output shaft extends through an axial through hole formed in the final stage gear of the gear reducer and an axial through hole formed in the rotor, and is rotatably supported by opposite end portions of the housing.
