To provide an air-conditioning exhaust port structure for a railway vehicle in which an exhaust port is provided on a lower side of a seat, and which decreases generation of noises around the exhaust port while suppressing foreign matters from being sucked into an exhaust duct.SOLUTION: An air-conditioning exhaust port structure (1) for a railway vehicle has: an exhaust port (110) provided on a lower side of a seat (200) installed on a floor (51) of a cabin (55); and a rectangular parallelepiped protective frame (20) comprising a cylindrical frame body (21) largely opening a bottom face and an upper face (23) provided on an end positioned on an opposite side of the bottom face of the frame body (21), and covering an opening part (113) of the exhaust port (110). The protective frame (20) is provided with plural ventilation holes (23a) only on the upper face (23), is arranged outside a region (UA) that is directly under a joint (201) of the seat (200), and air in the cabin (55) is made to flow linearly from the plural ventilation holes (23a) to the exhaust port (110) by passing through the frame body (21) (arrow Fx).SELECTED DRAWING: Figure 4

    【課題】座席の下側に排気口が設けられた鉄道車両用空調排気口構造において、排気ダクト内に異物が吸い込まれることを抑制しつつ、排気口付近で発生する騒音を低減すること。【解決手段】鉄道車両用空調排気口構造(1)において、車室(55)の床(51)に設置された座席(200)の下側に設けられた排気口(110)と、底面を大きく開口する筒状の枠本体(21)、及び、枠本体(21)の底面と反対側に位置する端部に設けられた上面(23)とを備え、排気口(110)の開口部(113)に被せられる直方体形状の保護枠(20)と、を有し、保護枠(20)は、上面(23)のみに複数の通気穴(23a)が設けられ、座席(200)の継ぎ目(201)の真下となる領域(UA)の領域外に配置されており、車室(55)の空気が複数の通気穴(23a)から排気口(110)まで枠本体(21)を通り抜けて直線的に流れるようにする(矢印Fx)。【選択図】図4
