Abstract
The torque transmission device includes side gears having a same axis of rotation coupled to rear wheels, a case disposed around the outer circumferential side of the side gears, and rotating around the axis of the side gears, and a pinion gear rotatably supported by the case and engaged with the side gears in a straddling manner. The side gears are spur gears having a different number of teeth, and the pinion gear is a spur gear driven by a motor and having an axis of rotation that is parallel to the axis of rotation of the side gears. Forming the side gears and pinion gear from spur gears advantageously allows the side gears to be compactly arranged along their axis of rotation.
