To provide a railway vehicle body structure in which a door frame and an outer panel, having thicknesses different from each other, are welded with weld strain suppressed.SOLUTION: A railway vehicle body structure includes: an outer panel provided with a door opening; and a door frame 20 welded to the door opening. The door frame 20 has: a body part 23 thicker than a plate thickness of the outer panel; and a recessed part 24 recessed to the outer panel side in a thickness direction. The outer panel and the door frame 20 are welded at a formation position of the recessed part 24 when viewed in the thickness direction.SELECTED DRAWING: Figure 5
【課題】互いに異なる板厚を有するドアフレームと外板とが溶接歪みを抑えた状態で溶接された鉄道車両構体を提供する。【解決手段】鉄道車両構体は、ドア用開口部が設けられた外板と、ドア用開口部に溶接されたドアフレーム20と、を備える。ドアフレーム20は、外板の板厚よりも厚い本体部23と、厚さ方向において外板側に窪んだ窪み部24と、を有する。外板とドアフレーム20とは、厚さ方向から見て窪み部24の形成位置で溶接されている。【選択図】図5
