The cooler body is attached to a body of the vehicle, while the air intake duct is attached to the cooler body, such that a strength of attachment of the air intake duct to the cooler body is lower than a strength of attachment of the cooler body to the body of the vehicle.

Vehicular cooling device

A vehicle includes a heat exchanging type cooling device includes an undercover disposed below the cooler body and having an air exhaust passage into which the ambient air discharged through the lower surface of the cooler body is introduced and through which the ambient air is exhausted into outside atmosphere, under a negative air pressure generated due to an air stream generated during running of the vehicle; and an elastically deformable sealing member in a closed form interposed between the air exhaust passage and the lower surface of the cooler body. The undercover is attached to the body of the vehicle, such that a gap is provided between the undercover and the lower surface of the cooler body, and such that the sealing member fluid-tightly closes the gap.

A vehicle drive device comprises: a power transmission mechanism transmitting a drive power from a drive power source to a plurality of wheels; a differential gear mechanism provided in the power transmission mechanism and distributing the drive power input from the drive power source to the plurality of wheels; a casing housing the power transmission mechanism; and an oil pump sucking a lubricating oil stored in the casing, and the device drives the oil pump in conjunction with rotation of the differential gear mechanism. In the device, a catch tank storing the lubricating oil is provided in the casing, an introduction path is formed in the casing for introducing the lubricating oil scooped up by the differential gear mechanism during backward running of a vehicle into the catch tank, and a discharge oil passage connected to a discharge port of the oil pump is connected to the catch tank.

Hybrid vehicle

A transmission unit is able to switch between a non-neutral state where power of an engine is transmitted via a path Kand a neutral state where power of the engine is not transmitted via the path K. A clutch is able to switch between an engaged state where power is transmitted from the engine to a first MG and a released state where transmission of power from the engine to the first MG is interrupted. When the transmission unit is controlled to the non-neutral state and, at the same time, the clutch is set to the released state, a vehicle is operable in series-parallel mode. When power is transmitted via the path Kby directly coupling the engine to the first MG by the clutch and the path Kis interrupted by controlling the transmission unit to the neutral state, the vehicle is operable in series mode.
