To control a flowing velocity of conditioning air by forming a blowout port of a nozzle portion in a peculiar opening shape, to enabling sending of conditioning air blown out from a blowout port toward a wide range even if it is a nozzle portion disposed on a vehicle outer end portion on a floor panel, and to improve comport while effectively using a space in a room.SOLUTION: In a structure of a vehicular air-conditioning duct 1, a duct portion 2 is disposed at a lower side of a front seat and at a floor end portion 4a at an outer side in a vehicle width direction positioned on a floor panel 4, a downstream side of the duct portion 2 extends from the floor end portion 4a toward the inner side in the vehicle width direction, and a downstream side end portion 2a of the duct portion 2 is provided with a nozzle portion 3 disposed at the floor end portion 4a. An opening portion 31a of a blowout port 31 of the nozzle portion 3 turns a vehicle vertical direction in a longitudinal direction, and has an opening shape with narrow opening width W1 at a lower side and a wide opening W2 with on an upper side.SELECTED DRAWING: Figure 2

    【課題】ノズル部の吹き出し口を特有の開口形状に形成することにより空調風の流速を制御し、フロアパネル上の車両外側端部に配置されたノズル部であっても、吹き出し口から吹き出される空調風を広範囲に向けて送ることができ、室内の空間を有効に利用しつつ、快適性を向上させる。【解決手段】前席シートの下側でフロアパネル4上に位置する車両幅方向外側のフロア端部4aにはダクト部2が配置され、ダクト部2の下流側は、フロア端部4aから車両幅方向内側へ向かって延びているとともに、ダクト部2の下流側端部2aには、フロア端部4aに配置されるノズル部3が設けられている車両用空調ダクト1の構造において、ノズル部3の吹き出し口31の開口部31aは、車両上下方向が長手方向となり、下側の開口幅W1が狭く、上側の開口幅W2が広くなる開口形状を有している。【選択図】図2
