Abstract
A novel drive train includes a motor, a differential gear unit, and a counter gear mechanism for transmitting the power of the motor to the differential gear unit. A universal joint for joining the differential gear unit to an axle shaft of a vehicle is arranged outward of one axial end of the motor to eliminate interference with the motor, and the differential gear unit is arranged adjacent the opposite axial end of the motor, radially overlapping the motor to the maximum, to thereby shorten the axial distance between the motor and the differential gear unit.
