PROBLEM TO BE SOLVED: To provide a railway vehicular duct structure which can assure a wide electric wiring and piping space even if a ceiling is not lowered.SOLUTION: A railway vehicular duct structure 2 provided between a ceiling 12 and a roof body structure 1B of a railway vehicle 1, in which first and second air conditioners 3, 4, which are embedded in the roof body structure 1B, are located near a center with respect to first and second vehicle end parts 18, 19 of the railway vehicle 1 and discharge conditioned air to the first and second vehicle end parts 18, 19 sides, first and second ducts 21, 22 supply said conditioned air in an opposite direction toward first and second side body structures 1C, 1D by first and second supply duct parts 211, 221, and thereafter, supply said conditioned air to first and second main duct parts 212, 222 which are located on one side of the first and second air conditioners 3, 4 and blow out said conditioned air to a vehicle central part. Thereafter, said blown-out air is sucked by first and second suction ports 32, 42 of the first and second air conditioners 3, 4, whereby said conditioned air can be widely spreaded in a passenger compartment 11.SELECTED DRAWING: Figure 1
【課題】天井を低くしなくても、配線配管スペースを広く確保できる鉄道車両用ダクト構造を提供する。【解決手段】鉄道車両1の天井12と屋根構体1Bとの間に設けられた鉄道車両用ダクト構造2において、屋根構体1Bに埋設される第1及び第2空調装置3,4が、鉄道車両1の第1及び第2車端部18,19より中央寄りに設置されて第1及び第2車端部18,19側に調和空気を吐出し、その調和空気を第1及び第2ダクト21,22が第1及び第2供給ダクト部211、221により第1及び第2側構体1C,1Dへ向かって反対向きに供給した後、第1及び第2空調装置3,4の片側に配置した第1及び第2メインダクト部212,222に供給し、車両中央部に吹き出し、その後、吹き出された空気が第1及び第2空調装置3,4の第1及び第2吸込口32,42に吸い込まれることにより、調和空気を車室11に広く行き渡らせるようにする。【選択図】図1
