PROBLEM TO BE SOLVED: To provide an air conditioning duct which improves structural strength and durability of a duct body including an inner corner part, and which can be favorably applied even to railway vehicles and the like on which vibration and impulse continuously act.SOLUTION: An air conditioning duct D is constituted by connecting a plurality of unit duct bodies 4 formed in a cylindrical shape in a linear row manner. The unit duct body 4 is formed in the cylindrical shape by folding a duct expansion body 18 including a plurality of duct peripheral walls 26 and first and second inner corner walls 27, 28. The first inner corner wall 27 is formed at one end of the duct expansion body 18, and the second inner corner wall 28 is formed at the other end. Joint surfaces G of the end parts the first and second inner corner walls 27, 28 are joined and fixed with each other by a connection material 37, and an inner corner part 35 which dents toward the inside of the duct is formed at the unit duct body 4.SELECTED DRAWING: Figure 1

    【課題】内隅部を備えているダクト体の構造強度と耐久性を向上して、振動や衝撃が継続的に作用する鉄道車両等であっても好適に適用できる空調用ダクトを提供する。【解決手段】筒状に形成される複数の単位ダクト体4を、直線列状に連結して構成した空調用ダクトDである。単位ダクト体4は、複数のダクト周壁26と第1、第2の内隅壁27・28を備えたダクト展開体18を折曲げて筒状に形成してある。ダクト展開体18の一端に第1内隅壁27を形成し、他端に第2内隅壁28を形成する。第1、第2の内隅壁27・28の端部の接合面Gどうしを連結材37で接合固定して、単位ダクト体4にダクト内部へ向かって凹む内隅部35を形成する。【選択図】図1
