Patent ID: 8333680

Claim:
A vehicle drive device, comprising: a speed change mechanism that shifts rotation of an input shaft and outputs the shifted rotation to an output shaft; a hydraulic transmission provided closer to an engine attachment side than the speed change mechanism is and including a turbine runner connected to the input shaft, a pump impeller, a front cover fixed to the pump impeller and a lock-up clutch; an electric motor having a rotor and a stator and connecting the rotor to the front cover of the hydraulic transmission; an engine power cut-off clutch that transmits or cuts off a driving force of the engine between the engine and the front cover; and the lock-up clutch engages or disengages between the turbine runner and the front cover, and includes a plurality of friction plates and a hydraulic actuator that presses the friction plates, and is disposed closer to the engine attachment side than the turbine runner; the engine power cut-off clutch includes a plurality of friction plates and a hydraulic actuator that presses the friction plates, and is disposed closer to the engine attachment side than the lock-up clutch is in the hydraulic transmission; the lock-up clutch actuator and the engine power cut-off clutch actuator are disposed so as to face each other so that the respective friction plates are pressed in opposing directions.
