To secure the aesthetics of a vehicle body structure by suppressing the deformation of a side outer plate due to welding distortion.SOLUTION: In a side outer plate 25 of a railway vehicle 1, a first divided outer plate 321 and a second divided outer plate 331 adjacent to each other in the track direction are butt-welded. A first transverse bone 322 and a second transverse bone 332 extend in the track direction on the inner surface 321a of the first divided outer plate 321 and the inner surface 331a of the second divided outer plate 331. A support assembly 50 extends along a butt weld part 43A of the first divided outer plate 321 and the second divided outer plate 331 and supports the butt weld part 43A. The support assembly 50 has: an abutting plate 51 abutting on the inner surface 321a of the first divided outer plate 321 and the inner surface 331a of the second divided outer plate 331; a reinforcing member 52 disposed between the first transverse bones 322 and the second transverse bones 332 and supporting the abutting plate 51; and an inner plate 53 connected to the first transverse bone 322 and the second transverse bone 332 and supporting the reinforcing member 52.SELECTED DRAWING: Figure 2
【課題】溶接歪みによる側外板の変形を抑えて車両構体の美観を確保すること。【解決手段】鉄道車両1の側外板25は、軌道方向に隣接して並ぶ第1分割外板321と第2分割外板331とが突き合わせ溶接されている。第1分割外板321の内面321aと第2分割外板331の内面331aには、第1横骨322と第2横骨332が軌道方向に延在している。支持組立50は、第1分割外板321と第2分割外板331との突き合わせ溶接部43Aに沿って延在し、突き合わせ溶接部43Aを支持する。支持組立50は、第1分割外板321の内面321aと第2分割外板331の内面331aとに当接する当接板51と、第1横骨322と第2横骨332との間に配設され、当接板51を支持する補強部材52と、第1横骨322と第2横骨332とに結合され、補強部材52を支持する内板53と、を有する。【選択図】図2
