To manufacture an end body structure with reduced man-hours in a railway vehicle body structure having a skirt squeezing shape.SOLUTION: A railway vehicle body structure 9 includes an end outer plate 21 and a side outer plate 40. The end outer plate 21 includes reinforcement parts 215A, 215B in which an end part in the vehicle body width direction is formed to be bent in the vehicle body vertical direction along an inner surface of the adjacent side outer plate 40. A wainscot lower part 42 of the side outer plate 40 is formed to be curved toward the interior of the vehicle and forms a skirt squeezing shape in which the lower vehicle body width is made smaller than the upper vehicle body width. Corner columns 25A, 25B are integrally installed inside the reinforcement parts 215A, 215B along the vehicle body vertical direction in which the lower part is bent toward the interior of the vehicle corresponding to the curved portion of the side outer plate 40. The end outer plate 21 has missing parts 217A, 217B in which the reinforcement parts 215A, 215B are omitted in an area corresponding to the lower end part 43 from the wainscot lower part 42 of the side outer plate 40 so as to expose the corner columns 25A, 25B from the missing parts 217A, 217B.SELECTED DRAWING: Figure 1
【課題】裾絞り形状の鉄道車両構体において、少ない工数で妻構体を製作すること。【解決手段】妻外板21と側外板40とを備え、妻外板21が、隣接する側外板40の内面に沿うように車体幅方向端部を車体上下方向に屈曲形成した補強部215A,215Bを備える鉄道車両構体9において、側外板40の腰板下部42が車内側に曲げ形成され、下部車体幅が上部車体幅より小さい裾絞り形状をなし、車体上下方向に沿って補強部215A,215Bの内側に一体的に設置され、側外板40の曲げ部分に対応して下部が車内側に屈折する隅柱25A,25Bを有し、妻外板21は、側外板40の腰板下部42から下端部43に対応する領域で補強部215A,215Bが欠落する欠落部217A,217Bを有し、隅柱25A,25Bを欠落部217A,217Bから露出させる。【選択図】図1
