To provide a drive device for a vehicle that can appropriately supply oil to an engagement member of an engagement device while favorably maintaining controllability of both the engagement device and a fluid coupling. A drive device for a vehicle includes an input member I drivingly connected to an internal combustion engine, an output member drivingly connected to a wheel, a rotary electric machine MG, a fluid coupling, an engagement device C1, and a case 3 housing these components. The engagement device C1 includes an engagement member 33, a pressing member 34 pressing and operating the engagement member 33, and a differential pressure generating chamber H2 that houses the engagement member 33 and receives oil supply so as to apply hydraulic pressure to a side of the pressing member 34 opposite to a side to which hydraulic pressure for operation is applied. A body portion housing chamber H4 housing a body portion of the fluid coupling and the differential pressure generating chamber H2 are structured as oil chambers independent of each other. The drive device further includes a coupling supply oil passage L6 supplying oil to the body portion housing chamber H4 and a differential pressure supply oil passage L2 supplying the oil to the differential pressure generating chamber H2.
