PROBLEM TO BE SOLVED: To provide a railway vehicle body structure capable of making a side body structure flat, securing strength at the periphery of a doorway, and suppressing corrosion adjacent to the doorway frame.SOLUTION: A side body structure 3 of a railway vehicle body structure 1 includes: an outside plate 11; a doorway frame 21 disposed on a vehicular inside of the outside plate 11 and at the periphery of an opening part 3a; and a bone member 31 disposed on the vehicular inside of the outside plate 11 and near the doorway frame 21. The bone member 31 and the doorway frame 21 each includes a rigid part protruding toward a vehicular inside, and an attachment part extending in both directions of the outside plate 11. The attachment part in the bone member 31 is overlapped on the vehicular inside of the outside plate 11 and a part of the attachment part forms an extension portion 35. The attachment part 22 in the doorway frame 21 is joined to, in a state overlapped on a vehicular inside of the attachment part in the bone member 31, the attachment part in the bone member 31 and an end part 11c on the opening part 3a side in the outside plate 11.SELECTED DRAWING: Figure 3
【課題】側構体のフラット化を実現でき、かつ出入口周辺の強度の確保及び出入口枠近傍での腐食の抑制が図られる鉄道車両構体を提供する。【解決手段】鉄道車両構体1の側構体3は、外板11と、外板11の車両内面側で開口部3aの周辺に配置された出入口枠21と、外板11の車両内面側で出入口枠21に隣接して配置された骨部材31と、を有し、骨部材31及び出入口枠21は、車両内側に向かって突出する剛性部と、外板11の面方向に延びる取付部とをそれぞれ有し、骨部材31における取付部は、外板11の車両内面側に重ね合わされていると共に、当該取付部の一部が張出部分35となっており、出入口枠21における取付部22は、骨部材31における取付部の車両内面側に重ね合わされた状態で、骨部材31の取付部及び外板11における開口部3a側の端部11cに接合されている。【選択図】図3
