PROBLEM TO BE SOLVED: To provide an air introduction device that can blow air strongly toward a desired direction while suppressing a burden on an air conditioner.SOLUTION: A branch part 14 of a blast duct 11 of an air introduction device 10 has three branched openings. A first branched opening is arranged at a region, at which a flow rate of air is fast, in an inner flow path at a lower end part of a main duct part 13. The total sum of areas of the branched openings are set to be equal to a cross section area of the main duct part 13. Branched duct parts 15-17 extend downward with the same cross section areas equal to the areas of the branched openings. An inner face of a blowing part 25 of an under cover 12 is enlarged in diameter in a vehicle width direction from a backside 26 side of the cover toward a front side of the cover.SELECTED DRAWING: Figure 2

    【課題】空調装置にかかる負担を抑えつつ、所望の方向へ空気を強く吹き出させる。【解決手段】空気導入装置10の送風ダクト11の分岐部14は、3つの分岐開口を有する。第1分岐開口は、メインダクト部13の下端部の内部流路のうち空気の流速が速い領域に配置される。各分岐開口の面積の総和は、メインダクト部13の断面積と同一になるように設定される。各分岐ダクト部15〜17は、各分岐開口の面積と同一の断面積で下方へ延びる。アンダーカバー12の吹き出し部25の内面は、カバー裏面26側からカバー表面側へ向かって車幅方向に拡径する。【選択図】図2
