To provide a ceiling material with a duct for a vehicle and a method of manufacturing the same, which allow the duct to be surely fixed to the ceiling material and which further allow the ceiling material to be fixed even to a place like a center region of an introduction base occupying a large area in the duct.SOLUTION: A ceiling material with a duct for a vehicle includes: a duct 4 molded by blow-molding into a cylindrical shape; a surrounded space S surrounded by a plate-shaped outer flange portion 5 having a gap ε between a side wall 41 of the duct 4 and a back surface 1b of a ceiling material 1 and extending outward from the duct, an opposed region 2 of the ceiling member 1, which is opposed to the outer flange portion 5, and a short-cylindrical peripheral wall W of a vertical wall forming portion of the duct 4, which extends from a peripheral edge of the outer flange portion 5 toward the ceiling member 1 or/and of a vertical wall forming portion of the ceiling material 1, which extends from a peripheral edge of the opposed region 2 toward the duct 4; plural through-holes α formed in the outer flange portion 5 to extend therethrough; and a hardener 71 of a hot-melt adhesive 7 closing the gap ε of the surrounded space S to fixedly connecting the opposed region 2 and the outer flange portion 5.SELECTED DRAWING: Figure 2
【課題】ダクトの天井材への確実な固定ができ、さらにダクトに占める面積が大きい導入基部の中央域といった箇所にも天井材への固定が可能な車両用ダクト付き天井材及びその製造方法を提供する。【解決手段】車両用ダクト付き天井材において、ダクト4が筒状のブロー成形ダクトにして、ダクト4の側壁部41から天井材1の裏面1bとの間に隙間εをあけてダクト外方へ延在した板状の外鍔部5と、外鍔部5と対向する天井材1の対向域部2と、外鍔部5の周縁から天井材1側へ向かうダクト4の起立形成部又は/及び対向域部2の周縁からダクト4側へ向かう天井材1の立壁形成部からなる短筒状の周壁部Wと、で取り囲まれた囲い空間Sと、外鍔部4に貫通形成された複数の通孔αと、囲い空間Sの隙間εを埋めて、対向域部2と外鍔部5とを結合固定しているホットメルト接着剤7の硬化物71と、を具備する。【選択図】図2
