PROBLEM TO BE SOLVED: To provide an air blowout device for a vehicle capable of enhancing Coanda effect.SOLUTION: An air blowout device for a vehicle comprises: a ventilation passage X for introducing conditioned air blown out of an air conditioning unit 20 for the vehicle into a vehicle interior via an air outlet; and a flap 12 disposed in the ventilation passage X. The flap 12, in response to switching from a defrost mode to another mode, makes a flow passage cross section area of a rear ventilation part X1 formed between the flop 12 and an inner wall surface of the ventilation passage X, smaller than that at the defrost mode to make a flow rate of air flowing in the ventilation part faster than that at the defrost mode. A curved surface 11f is formed on the inner wall surface on the rear ventilation part X1 side of the ventilation passage X on the upstream side of the flap 12, for introducing the conditioned air to the ventilation part X1. The curved surface 11f is curved so as to approach the flap 12 as approaching the rear ventilation part X1, away from the air conditioning unit 20 for the vehicle.SELECTED DRAWING: Figure 4

    【課題】コアンダ効果を向上させることのできる車両用空気吹き出し装置を提供する。【解決手段】車両用空気吹き出し装置は、車両用空調装置20から吹き出された空調風を吹出口を介して車室内に導く通風路Xと、通風路X内に配置されるフラップ12とを備える。フラップ12は、デフロストモードから別モードに切り替える際、フラップ12と通風路Xの内壁面との間に形成される後方側通風部分X1の流路断面積をデフロストモードのときよりも狭くすることにより、通風部分を流れる気流の流速をデフロストモードのときよりも速くさせる。フラップ12よりも上流側における通風路Xの後方側通風部分X1側の内壁面には、空調風を通風部分X1に導く湾曲面11fが形成されている。湾曲面11fは、車両用空調装置20から後方側通風部分X1に向かうほど、フラップ12に近づくように湾曲している。【選択図】図4
