Abstract: A power transmission device includes a planetary gear, a reduction gear connected downstream of the planetary gear, a parking lock mechanism including a parking pawl configured to lock one rotation element of the planetary gear, and a barrier wall positioned between the planetary gear and the reduction gear. The parking pawl is rotatably supported on the barrier wall.

Abstract: A hybrid vehicle drive device includes a transmission coupled to the engine output shaft of an engine, a final reduction gear coupled to the transmission output shaft of the transmission, a drive shaft coupled to the final reduction gear, and a power transmission mechanism that transmits the rotation of an electric motor to the final reduction gear. The hybrid vehicle drive device includes a transaxle case accommodating the transmission, the final reduction gear and the power transmission mechanism and having a mounting surface for mounting the engine and the electric motor. The transaxle case is formed by an engine-side converter housing, a transmission-side transmission case, and a middle wall attached to the converter housing and separating the converter housing from the transmission case, the power transmission mechanism being housed between the converter housing and the middle wall.

Abstract: A hybrid vehicle drive device includes a power transmission mechanism including a transmission coupled to an engine output shaft, a clutch coupled to a transmission output shaft, a first gear coupled to a clutch output shaft, a final reduction gear that constantly meshes with the first gear, a drive shaft coupled to the final reduction gear, a first rotary element coupled to an electric motor, and a second rotary element that meshes with the final reduction gear and rotates in accordance with the rotation of the rotary element. The power transmission mechanism is disposed so that, when viewed from the rotational axis direction of each gear, a line that connects the rotational axis of the first rotary element and the rotational axis of the second rotary element is inclined to the first gear side in relation to the vertical direction of the vehicle when mounted to a vehicle.
