A drive device for a vehicle, having an engine power disengaging clutch mounted in a lockup clutch-equipped fluid power transmitting device, wherein controllability and torque transmission capacities of both the clutches are increased, the amount of heat generation of friction materials when the clutches are engaged is reduced, the drive device allows a fluid drive device to be configured withoutan increase in the size thereof, and the drive device is configured without an increase in the size thereof. The lockup clutch and the engine power disengaging clutch are respectively formed as multi-plate clutches having actuators. Friction plates of the lockup clutch are provided on the outer diameter side of a torus. The engine power disengaging clutch is formed to have a smaller diameter thanthe lockup clutch. The engine power disengaging clutch is provided in a torque converter. On the outer diameter side of the engine power disengaging clutch, a motor generator is mounted overlapping axially the friction plates of the engine power disengaging clutch.
