PROBLEM TO BE SOLVED: To provide a ceiling structure of a railway vehicle that comprises a flow regulating plate of a transverse fan which can be continuously installed in a longitudinal direction of the vehicle without interfering with grip bars and hanging rings and the like installed in a ceiling plate of the railway vehicle and can be safely and easily attached and detached.SOLUTION: The ceiling structure of a railway vehicle comprises: a ceiling plate 2 which partitions a roof body structure 1 and a passenger room S; a pair of left and right partition plates 3 which connect the roof body structure to the ceiling plate at the vicinity of the center in the lateral direction of the vehicle; a transverse fan 5 stored in a center space 4 formed between both partition plates; and a flow-regulating plate 6 which is attached detachably, with a fastener 81, to an opening part 21 formed in the ceiling plate below the transverse fan. The air-regulating plate is provided with a fall prevention member 7 which contacts a receiving portion 22 formed in the opening part 21 when an upper end part 61 thereof moves downward from a lower end part 62B of the other air-regulating plate 6B installed in the longitudinal direction of the vehicle. The contacting state of the fall prevention member with the receiving portion can be released by moving the air-regulating plate in the longitudinal direction of the vehicle while contacting the member with the receiving portion.SELECTED DRAWING: Figure 1
【課題】鉄道車両の天井板に設置されているにぎり棒や吊り輪等と干渉することなく車両前後方向に連続的に設置でき、安全かつ簡単に着脱できる横流ファンの整風板を備えた鉄道車両の天井構造を提供する。【解決手段】屋根構体1と客室Sとを区画する天井板2と、車両左右方向の中央付近において屋根構体と天井板とを連結する左右一対の仕切板3と、両仕切板間に形成される中央空間4内に収容される横流ファン5と、横流ファンの下方で天井板に形成された開口部21に締結具81によって着脱可能に装着される整風板6とを備えた鉄道車両の天井構造である。整風板には、その上端部61が車両前後方向に設置された他の整風板6Bの下端部62Bより下方へ移動したとき、開口部21に形成された受け部22と当接する落下止め部材7を備え、落下止め部材は、受け部と当接した状態で、整風板を車両前後方向へ移動させることによって受け部との当接状態が解除される。【選択図】 図1
