To provide a side wall structure of a railway vehicle in which a side structure can be retracted while efficiently absorbing an impact regardless of the magnitude of the impact.SOLUTION: A side wall structure 1 of a railway vehicle having an off-set collision countermeasure structure is provided with a buckling section 8 between a corner strut 4 and a side frame structure 2. The buckling section 8 extends in a height direction so as to include an area corresponding to height of a pier panel section 6 included in the side structure 2. An upper end of the buckling section 8 is separated from a ceiling and a lower end is separated from a floor. Compression strength of the buckling section 8 is set to be smaller than that of the side structure 2 in a longitudinal direction of the vehicle.SELECTED DRAWING: Figure 1

    【課題】衝撃の大きさに関わらず、効率的に衝撃を吸収しながら側構体を退避させることが可能な鉄道車両の側壁構造を提供する。【解決手段】オフセット衝突対策構造を有する鉄道車両の側壁構造1では、隅柱4と側構体2との間に座屈部8が設けられている。座屈部8は、側構体2のうち吹寄部6の高さに相当する領域を含むように高さ方向に延びている。この座屈部8の上端側は天井から離隔しており、下端側は床から離隔している。車両長手方向に対する圧縮強度は、側構体2よりも座屈部8の方が小さくなるように設定されている。【選択図】図1
