To solve a problem that a certain position of an exhaust port of an exhaust duct and a certain size of the exhaust port may cause air exhausted from the exhaust port to flow into the exhaust duct from the exhaust port again to flow reversely in the exhaust duct.SOLUTION: A suction port 61 that is a vehicle exterior part side opening of a suction duct 60 opens to the vehicle rear side. An exhaust port 92 that is a vehicle exterior part side opening of an exhaust duct 90 opens to the vehicle lower side. In a position located at the front side relative to the exhaust port 92 and overlapping with the exhaust port 92, a protruding part 81 protruding to the vehicle lower side further than the exhaust port 92 is located. A value obtained by dividing a length L that is a distance from a rear end on a protruding apical surface of the protruding part 81 to a rear end of the exhaust port 92 as seen in a vehicle fore and aft direction by a height H that is a distance from a lower end of an oil cooler 70 to the rear end on the protruding apical surface of the protruding part 81 as seen in a vehicle vertical direction is smaller than 3.5.SELECTED DRAWING: Figure 2

    【課題】排気ダクトの排気口を設ける位置や排気口の大きさによっては、排気口から排気された空気が、再び排気口から排気ダクト内に入って排気ダクト内を逆流することがある。【解決手段】吸気ダクト60の車両外部側の開口である吸気口61は、車両後側に向けて開口している。排気ダクト90の車両外部側の開口部である排気口92は、車両下側に向けて開口している。排気口92よりも前側であって車幅方向において排気口92と重複する位置においては、排気口92よりも車両下側にまで突出する突出部81が位置している。車両前後方向における突出部81の突出先端面における後端から排気口92の後端までの距離である長さLを、車両上下方向におけるオイルクーラ70の下端から突出部81の突出先端面における後端までの距離である高さHで除した値が3.5よりも小さくなっている。【選択図】図2
