A hybrid vehicle in which a sufficient amount of oil can be discharged when an internal combustion engine is operated at low speeds, and which can prevent the oil from being excessively discharged when the internal combustion engine is operated at high speeds. The hybrid vehicle has an internal combustion engine, an electric motor, a generator, and an output shaft for transmitting drive force to drive wheels. The hybrid vehicle also has a differential gear unit which is connected to the internal combustion engine, the electric motor, the generator and the output shaft, a rotating unit, and rotation transmitting device for selectively transmitting to the rotating unit whichever is faster of the rotation transmitted from the internal combustion engine to the differential gear unit and the rotation transmitted from the differential gear unit to the generator. With this structure, the rotating unit can be operated by the electric motor when the internal combustion engine is stopped. Moreover, the faster one of the rotation transmitted from the internal combustion engine to the differential gear unit and the rotation transmitted from the differential gear unit to the generator is selected and transmitted to the rotating unit. Accordingly, the rotating unit can be rotated even when the internal combustion engine is operated at low speeds in an idle state or the like.
