A fan structure is provided with a fan, a fan support, a base, and a motor. The fan is provided with a rotational shaft rotatable about a rotational shaft, and a blade coupled to the rotational shaft to rotate about the rotational axis together with the rotational shaft. The fan support rotatably supports the rotational shaft. The base slidably supports the fan support so as to be slidable in the sliding direction. The motor includes a motor main body supported by a fan support opposite to the rotational shaft of the fan in the axial direction along the rotational axis, and a motor rotational shaft connected to the rotational shaft so as to rotate the rotational shaft.

A power supply device includes a plurality of battery cells each including an outer covering can in a prismatic shape, a pair of end plates that cover both end surfaces of a battery stack in which the plurality of battery cells are stacked, a plurality of bind bars each formed into a plate shape extending in a stacking direction of the plurality of battery cells, the plurality of bind bars being respectively disposed on opposite side surfaces of the battery stack to fasten end plates to each other, heat radiation plate placing the battery stack on its upper surface side for releasing heat from the battery stack, and heat transfer sheet interposed between an upper surface of heat radiation plate and a lower surface of the battery stack to bring heat radiation plate and the battery stack into a thermally coupled state, wherein low friction slide layer with a friction resistance smaller than a friction resistance of the upper surface of heat transfer sheet is provided between heat transfer sheet and the plurality of battery cells.

A vehicle power unit room structure is provided including a motor that is disposed inside a power unit room and that is configured to transmit drive force to a drive wheel, a compressor that is disposed adjacent to the motor in a vehicle width direction so as to overlap with the motor as viewed along the vehicle width direction, and a power supply section that is configured to supply power supplied from a power source to the motor and the compressor, and that is disposed at a vehicle upper side of the compressor so as to overlap with the compressor as viewed along a vehicle vertical direction.
