PROBLEM TO BE SOLVED: To improve workability of joining an outer plate and a side beam and improve the appearance of a railway vehicle.SOLUTION: In a coupling structure 10 between a side structure and a base frame, the side structure 12 includes an outer plate 14 and a plurality of side posts 16, and the base frame 20 includes a side beam 22 including a channel part 24 and a first flange part 32, and a cross beam 40. In the channel part 24, a cross section orthogonal to an extension direction forms a U shape opening toward the outside of a vehicle. Because flat plates, such as the outer plate 14 and the first flange part 32 of the side beam 22, are joined together and the joining operation is not obstructed by the cross beam 40 or the like, joining workability can be improved. In addition, because the joining is performed in a state in which a lower end position of the outer plate 14 extends to at least a lower end position of the first flange part 32, a step is not formed between the outer plate 14 and the side beam 22, and it is possible to improve the appearance of a railway vehicle.SELECTED DRAWING: Figure 1
【課題】外板と側梁との接合の作業性を向上させると共に、鉄道車両の見栄えを向上させる。【解決手段】側構体と台枠との結合構造10は、側構体12が、外板14と複数の側柱16とを含んでおり、台枠20が、チャネル部24及び第1フランジ部32を含む側梁22と横梁40とを含んでいる。チャネル部24は、延在方向と直交する断面が、車両外側へ開口するコの字状を成している。そして、外板14と側梁22の第1フランジ部32という、平板同士が接合され、又、横梁40等によって接合作業が阻害されることもないため、接合の作業性を向上することができる。更に、外板14の下端位置が、少なくとも第1フランジ部32の下端位置まで延びた状態で、上記の接合が行われるため、外板14と側梁22との段差が形成されることはなく、鉄道車両の見栄えを向上することが可能となる。【選択図】図1
