A series hybrid drive unit that is downsized while improving power transmission efficiency. In the series hybrid drive unit, a generator is driven by an engine, and a motor is operated by electricity generated by the generator. Torque generated by the generator is delivered to drive wheels through a final reduction unit. An input member that is rotated by a torque of the engine, and that is arranged parallel to a rotational center axis Og of the generator. The generator and the motor are arranged parallel to each other while keeping a predetermined clearance, and the final reduction unit is arranged parallel to the motor. The input member and the generator are connected through a first wrapping transmission mechanism, and torque of the motor is transmitted to a final reduction unit through a second wrapping transmission mechanism.
