Abstract
A drive device for a vehicle configured between an internal combustion engine and a wheel. The drive device includes a rotary electric machine, and an engagement device connecting the drive device to the engine by a fluid coupling using hydraulic pressure. A case houses at least a portion of the drive device and includes a support wall extending radially, and a cylindrical projecting portion projecting from the support wall toward a side in an axial second direction that is in a direction opposite to the axial first direction. The engagement device includes an operating oil pressure chamber supplied with the hydraulic pressure. A rotor member of the rotary electric machine is radially supported by the cylindrical projecting portion in a rotatable state via a support bearing. The cylindrical projecting portion is formed with an operating oil supply passage supplying oil to the operating oil pressure chamber.
