Abstract: An air guiding unit has a shroud having a vent hole, an air guiding duct, and a valve housed in the air guiding duct. A radiator, an engine cooling heat exchanger, and a blower are fixed to the shroud. The shroud guides an air flowing into an engine room from an engine room opening and passing through the radiator and the engine cooling heat exchanger. The air guiding duct has a first opening, which is connected to the vent hole of the shroud, and a second opening, which is open in the engine room toward a rear space defined on a rear side of the engine. The air guiding duct therein has a duct interior channel through which the air flows between the first opening and the second opening. The valve is configured to increase and decrease an opening degree of the duct interior channel.
