To provide an air-conditioning duct structure for an automobile capable of attaining request properties for both when air-conditioning is necessary and when it is unnecessary at a rear seat.SOLUTION: An air-conditioning duct structure for an automobile includes: an underfloor duct that is a pipe line disposed below a floor surface of a cabin and guides air-conditioning air of an air-conditioning unit from a front side of the cabin via a rear end opening to a rear seat side; a duct opening formed on the floor surface; and a lifting/lowering duct fitted to the duct opening to enable lifting/lowering and having a duct side wall and an upper surface for closing an upper part of the duct side wall. The duct side wall of the lifting/lowering duct includes: a communication hole opened at a front side or a lateral side of the cabin; and a blowout port located above the communication hole and opened at a rear side of the cabin. A lifting/lowering position of the lifting/lowering duct includes: a ventilation position in which the underfloor duct and the lifting/lowering duct communicate with each other via the rear end opening and the communication hole while the blowout port is exposed to the upper side of the floor surface; and an accommodation position in which the upper surface is located at a lower side of the floor surface and the rear end opening is closed by the duct wall at an upper side of the communication hole.SELECTED DRAWING: Figure 1

    【課題】後席での空調の必要時と不要時の双方の要求特性を両立する自動車用空調ダクト構造を提供する。【解決手段】車室のフロア表面よりも下方に配置される管路で、車室の前方から後端開口を経て後席側に空調ユニットの空調風を案内する床下ダクトと、フロア表面に形成されたダクト用開口と、ダクト用開口に昇降自在に嵌められて、ダクト側壁と、ダクト側壁の上部を塞ぐ上面とを有する昇降ダクトとを備える。昇降ダクトのダクト側壁は、車室の前方側又は側方側に開口する連通孔と、連通孔よりも上部で、車室の後方側に開口する吹き出し口とを有する。昇降ダクトの昇降位置は、吹き出し口がフロア表面よりも上方に露出した状態で、後端開口及び連通孔を介して床下ダクトと昇降ダクトとが連通される通風位置と、上面がフロア表面以下の下方に位置し、後端開口を連通孔よりも上部のダクト側壁で塞ぐ収納位置とを有する。【選択図】図1
