Patent ID: 8836187

Claim:
A vehicle drive device, comprising: an input member drivingly coupled to an internal combustion engine; an output member drivingly coupled to a wheel; a rotating electrical machine; a fluid coupling; and a case containing at least the rotating electrical machine and the fluid coupling, wherein the fluid coupling includes a coupling input-side member, and a coupling output-side member that is paired with the coupling input-side member, the rotating electrical machine includes a rotor main body and a rotor support member that extends inward in a radial direction from the rotor main body on an axial first direction side, the axial first direction side being one side in an axial direction with respect to the coupling input-side member, and supports the rotor main body, the rotor main body being rotatably supported in the radial direction by the case via a support bearing, a power transmission member is formed by coupling at least the rotor support member and the coupling input-side member together so that at least the rotor support member and the coupling input-side member rotate together, and a movement restricting mechanism that restricts axial movement of the power transmission member toward the axial first direction side is provided, the movement restricting mechanism has a restricting bearing that rotatably supports the power transmission member separately from the support bearing, and an axial support portion of the case that supports the restricting bearing from the axial first direction side, and a distance by which the power transmission member is movable relative to the case in the axial direction in a region where the restricting bearing is provided is set to a value smaller than a distance by which the power transmission member is movable relative to the case in the axial direction in a region where the support bearing is provided.
