Abstract
A power train device is provided with an electric motor including a cylindrical stator wound with electric oils and a cylindrical rotor which is disposed radially inwardly of the stator and rotated by energization of the electric coils. A reduction gear mechanism is provided for reducing the number of rotations of the rotor, and a differential gear mechanism is provided for supplying rotation power from the output of the reduction gear mechanism to a pair of drive shafts connected to each wheel and for absorbing a differential between the wheels. A cover covers the electric motor, the reduction gear mechanism and the differential gear mechanism, and the reduction gear mechanism is mounted radially inwardly of the cylindrical rotor.
