To provide a railway vehicle air-conditioning duct installation structure by which an air-conditioning duct is simply fitted and a fitting position of an interior panel to cover the air-conditioning duct is easily adjusted.SOLUTION: A railway vehicle air-conditioning duct installation structure 10 comprises an air-conditioning duct 3 connected to a branch duct 21 communicated to an air conditioner 2 of a railway vehicle 1 and extending from a neighborhood of a floor to a lower part of an upper cargo shelf 55, and a wall surface 31 of the air-conditioner duct near the room is formed to come into contact with or approach an interior panel 54 covering from an inside of the room. A lower end part 32 of the air-conditioning duct is connected to a branch duct via an elastic member 7, and the interior panel is fixed to a side structure 52 in a state of a pressing force from an upper side. The air-conditioner duct comprises a metal fitting linkage 41 horizontally movably linked to a receiving metal fitting 6 extending from the interior panel to the side structure, and the metal fitting linkage aims a drop prevention function of the air-conditioner duct in a state the interior panel is fixed to the side structure.SELECTED DRAWING: Figure 1

    【課題】空調ダクトの取付けが簡単にできると共に、空調ダクトをカバーする内装パネルの取付位置の調整が容易にできる鉄道車両用空調ダクト取付構造を提供する。【解決手段】鉄道車両1の空調装置2と連通された分岐ダクト21に接続され、床近傍から上方の荷棚55下部まで延設された空調ダクト3を備え、空調ダクトの室内寄り壁面31は、室内側からカバーする内装パネル54に当接又は近接するように形成された鉄道車両用空調ダクト取付構造10である。空調ダクトの下端部32は、弾性部材7を介して分岐ダクトに接続され、内装パネルは、空調ダクトを上方から押圧した状態で側構体52に固定されている。空調ダクトには、内装パネルから側構体側に延設された受金具6に対して水平方向へ移動可能に連係された連係金具41を備え、連係金具は、内装パネルが側構体に固定された状態では、空調ダクトの落下防止機能を担う。【選択図】 図1
