A driving force transmission unit consists of a gear unit engaging with the motor axes of two AC motors, and a bevel gear for transmitting the driving forces of the two AC motors to an axle. Wheels are installed on both ends of the axle. The output voltage of a battery of low voltage is transformed to AC voltage by a DC/AC transformer, and the transformed voltage is supplied to the two AC motors. Then, the driving forces of the two AC motors are synthesized to be transmitted to the axle.
