Abstract: A power transmission device of a four-wheel drive electrically driven vehicle comprises a transverse engine that is supported on one right side surface of two side surfaces of the gear case, and a motor that is supported on the other left side surface of the two side surfaces of the gear case. The power transmission device includes a transfer case that is supported by a gear case and the distributes power from a power source between the left and right front wheels and the left and right rear wheels. The transfer case wraps around from the side surface to a rear surface of the gear case, as seen from above, and outputs power to the left and right rear wheels from the rear surface side of the gear case.

Abstract: In a power transmission device of a four-wheel drive electrically driven vehicle, the power source includes a transverse engine supported on one side surface of a gear case, and a motor supported on the other side surface. A transfer case is supported on the same side surface of the gear case as the motor. The transfer case has a transfer input shaft arranged in the vehicle width direction, a transfer output shaft arranged in the longitudinal direction of the vehicle, a bevel gear pair and a transfer gear pair. The bevel gear pair and the transfer gear pair transmit power by changing a rotational axis direction to an essentially orthogonal direction between the transfer input shaft and the transfer output shaft. An output shaft gear provided on the transfer output shaft of the transfer case is disposed in a position overlapping the gear case in a vehicle width direction.

Abstract: A base plate 20 is provided with an oil inflow hole 20b in the form of a through-hole. The oil inflow hole 20b includes an area overlapping oil inlet communication holes 1 of plates 5 within a region inside an annular grove 20a of the base plate 20, and has a planar shape extending beyond the outer rim of the overlapping area. Thus, in the base plate constituting a contact end when the oil cooler is mounted to the engine block, a decrease in communication resistance of the oil communication hole provided therein as well as a smooth circulation of oil is achieved.
