Provided is a vehicle drive device that makes it possible to maintain quietness at the time of acceleration while obtaining a strong propulsive force. The vehicle drive device (10) is provided with: an input member (14) connected to an engine (11); a first clutch (16) for connecting and disconnecting power from the input member (14); an output member (27) connected to wheels (29); a differential device (20) comprising a rotating element (22) connected to the input member (14), a rotating element (21) connected to a first rotating electric machine (11), and a rotating element (23) connected to the output member (27) and to a second rotating electric machine (12); a second clutch (30) that connects any two of the rotating elements; and a switching device (60) for switching the state of the second clutch (30). The second clutch (30) allows two of the rotating elements to rotate relative to each other when the orientation of the direction of relative rotation thereof is a second direction. The second clutch (30) connects two of the rotating elements when the orientation of the direction of relative rotation thereof is a first direction.
