PROBLEM TO BE SOLVED: To enhance heat insulation performance of an air conditioner duct.SOLUTION: An air conditioner duct comprises left and right duct bodies extending toward both sides in a vehicle width direction. A heat insulation sheet 14 is wound around a left side duct body 12 L among the left and right duct bodies. The air conditioner duct comprises a projection plate part 18 projecting downward from an undersurface 12a of a central part 23 of a lower plate part 19 among the undersurface 12a of the lower plate part 19 of the duct body 12 L. The heat insulation sheet 14 is wound around the duct body 12 L and the projection plate part 18. In a state of winding the heat insulation sheet 14 around the duct body 12 L and the projection plate part 18, a front side space 32 is partitioned between a front inclined sheet part 14d, the undersurface 12a of the lower plate part 19, and a front surface 31 of the projection plate part 18. A rear side space 34 is partitioned between a rear inclined sheet part 14e, the undersurface 12a of the lower plate part 19, and a rear surface 33 of the projection plate part 18.SELECTED DRAWING: Figure 4
【課題】エアコンダクトの断熱性を高める。【解決手段】エアコンダクトは、車幅方向両側へ向かって延びる左右のダクト本体を有する。左右のダクト本体のうち左側のダクト本体12Lには、断熱シート14が巻回される。エアコンダクトは、ダクト本体12Lの下板部19の下面12aのうち、下板部19の中央部23の下面12aから下方へ突出する突出板部18を有する。断熱シート14は、ダクト本体12L及び突出板部18に巻回される。ダクト本体12L及び突出板部18に断熱シート14が巻回された状態で、前傾斜シート部14dと下板部19の下面12aと突出板部18の前面31との間には、前側空間32が区画形成される。また、後傾斜シート部14eと下板部19の下面12aと突出板部18の後面33との間には、後側空間34が区画形成される。【選択図】図4
