To provide a vehicular wind guide structure which can achieve both of reduction of air resistance of a vehicle and cooling of an object to be cooled located behind an internal combustion engine.SOLUTION: A vehicular wind guide structure has: a radiator 110 inclined rearward; and a wind guide duct 120. An inflow port 121 of the wind guide duct 120 has: an internal combustion engine front side panel 121A disposed at a front side of the internal combustion engine 40 and extending to an area below the internal combustion engine 40; a radiator lower side panel 121B extending from an area below the radiator 110 to the area below the internal combustion engine 40; and side face panels (121R, 121L) disposed at left and right sides of the internal combustion engine front side panel 121A and the radiator lower side panel. An outflow port of the wind guide duct 120 is branched into an engine room internal discharge port 122, which discharges a part of wind guided from the inflow port 121 to the area below the internal combustion engine 40 toward object positions to be cooled 41, 42, 60 located behind the internal combustion engine 40, and a vehicle external discharge port 123, which discharges residual wind to the outside of a vehicle 1.SELECTED DRAWING: Figure 1
【課題】車両の空気抵抗の低減と、内燃機関の背後にある冷却対象箇所の冷却と、を両立できる車両用導風構造を提供する。【解決手段】後傾されたラジエータ110と、導風ダクト120と、を有し、導風ダクト120の流入口121は、内燃機関40の前側に配置されて内燃機関40の下方に向けて延ばされた内燃機関前側パネル121Aと、ラジエータ110の下方から内燃機関40の下方に向けて延ばされたラジエータ下側パネル121Bと、内燃機関前側パネル121Aとラジエータ下側パネルの左右に配置された側面パネル(121R、121L)と、を有し、導風ダクト120の流出口は、流入口121から内燃機関40の下方へと導いた風の一部を、内燃機関40の後方にある冷却対象箇所41、42、60に向けて吐き出すエンジンルーム内吐出口122と、残りの風を、車両1の外部へ向けて吐出する車両外吐出口123と、に分岐されている。【選択図】図1
