PROBLEM TO BE SOLVED: To provide an auxiliary running gear for a vehicle, which is excellent in ease of installation in a vehicle, simplification of a device structure, and economy, and can facilitate the starting of a large-displacement engine. SOLUTION: This gear includes a clutch which connects a carrier 425 of a planetary gear mechanism 420 with the engine 1, a sun gear 426 with a generator motor 440, a ring gear 424 with a compressor 450 respectively, and restrain the compressor 450 by a lock structure 460, and revolves and disengages the carrier 425 integrally with the ring gear 424. Thus, the following four operations can be performed: compressor drive during idle stopping by the single generator motor; engine start by the generator motor; generator motor drive by the engine; the generator motor drive/compressor drive. A rotary electric machine and its driving circuit can be also unified, therefore a simple structure can be attained, and the starting of the large-displacement engine can be performed without needing the generator motor of large size and torque.
