PROBLEM TO BE SOLVED: To cool a component mounted on a vehicle front side of a dash panel by effectively using an air flow flowing into an engine room.SOLUTION: In a vehicular air introduction structure S, an upper end portion of a heat insulator 60 is an inclined portion 62 bent to a vehicle front side. The inclined portion 62 is disposed separately to a vehicle lower side of a hood silencer 32 provided on a hood 30, and formed with an opening portion 64 opened to a vehicle front side by the inclined portion 62 and the hood silencer 32. At both side parts in a vehicle width direction of the hood silencer 32, a pair of air introduction guide 70 is protrusively formed to a vehicle lower side, and an air flow F flowing to a vehicle rear side along the hood silencer 32 in an engine room ER is guided to the opening portion 64 by the pair of the air introduction guide 70, and guided into a space G between the heat insulator 60 and a dash silencer 54 of the inclined portion 62. Therefore, a mounting component 56 is cooled by effectively using the air flow F.SELECTED DRAWING: Figure 1 【課題】エンジンルーム内に流れ込む空気流を有効に活用してダッシュパネルの車両前側に搭載された部品を冷却する。【解決手段】車両用導風構造Ｓでは、ヒートインシュレータ６０の上端部が車両前側に屈曲された傾斜部６２とされている。この傾斜部６２は、フード３０に設けられたフードサイレンサ３２の車両下側に離間して配置されて、傾斜部６２とフードサイレンサ３２とによって車両前側へ開口された開口部６４が形成されている。また、フードサイレンサ３２の車幅方向両側部分には、一対の導風ガイド７０が車両下側へ突出形成されており、エンジンルームＥＲ内をフードサイレンサ３２に沿って車両後側へ流れる空気流Ｆが、一対の導風ガイド７０によって開口部６４に導かれて、傾斜部６２によってヒートインシュレータ６０とダッシュサイレンサ５４との間の空間Ｇに導かれる。これにより、空気流Ｆを有効に活用して搭載部品５６を冷却することができる。【選択図】図１
