To solve the problem that an air-conditioning duct is heavy because the air-conditioning duct assembled into a ceiling unit of a railway vehicle has a structure which is formed by a strength body such as an aluminum plate or an iron plate and has a heat insulation material pasted inside.SOLUTION: In an air-conditioning duct for a railway vehicle including a plenum duct having an opening on a passenger cabin side, and a compressed-air duct partitioned by a partition wall having a communication hole communicating with the plenum duct, an upper wall, a lower wall and opposing side walls of the air-conditioning duct are respectively connected, and in the partition wall, an upper edge and a lower edge are connected to the upper wall and the lower wall. Since the air-conditioning duct characterized by the matter that the upper wall, the lower wall, the opposing side walls, and the partition wall are formed of a plate-like heat insulation materials can omit a strength body, an air-conditioning duct which is light in weight and has a fixed structure strength can be provided.SELECTED DRAWING: Figure 1

    【課題】鉄道車両の天井ユニットに組み込まれる空調ダクトは、アルミ板や鉄板といった強度体で構成した後、内側に断熱材を貼り付けた構造となっていた。そのため、空調ダクトが重いという課題があった。【解決手段】客室側に開口部を有するプレナムダクトと、前記プレナムダクトとの間を連通させる連通孔を有する仕切り壁で仕切られた圧縮空気ダクトを有する鉄道車両の空調ダクトであって、前記空調ダクトの上壁と、下壁と、対向する側壁がそれぞれ接続され、前記仕切り壁は、上端と下端が前記上壁と前記下壁に接続され、前記上壁と、前記下壁と、前記対向する側壁と、前記仕切り壁が板状断熱材で形成されていることを特徴とする鉄道車両の空調ダクトは、強度体を省略できるため、軽く、一定の構造強度を有する空調ダクトを提供することができる。【選択図】図1
