To provide a railway vehicle body structure having an end body structure with enhanced rigidity.SOLUTION: A reinforcement structure extends obliquely in both the width direction and the height direction from an end body structure included in a railway vehicle body structure. One reinforcement structure preferably includes a portion extending radially toward the center of a through passage port of the end body structure. The other reinforcement structure preferable has, if it is not provided, a portion extending in a direction intersecting with a displacement contour line shown by the end body structure due to a load applied on the railway vehicle body structure. The end body structure includes an extruded shaped member whose rigidity is enhanced in the extrusion direction and the extrusion direction is oblique with respect to both the width direction and the height direction. The extrusion direction of the other extruded shaped member is converged to the center of the through passage port of the end body structure. It is preferable that a part of the extruded shaped member included in the end body structure or all the extrusion directions are aligned in the direction intersecting with the displacement contour line with reference to the displacement contour line in the end body structure due to a load applied on the railway vehicle body structure.SELECTED DRAWING: Figure 2

    【課題】 妻構体の剛性を高めた鉄道車両構体を提供できる。【解決手段】 鉄道車両構体を構成する妻構体に、幅方向と高さ方向との何れに対しても斜め方向に補強構造体が延設される。ある補強構造体は妻構体の貫通路口の中心に向かって放射状に延設される箇所を有すると良い。他の補強構造体は、それがない場合に当該鉄道車両構体に負荷される荷重によって妻構体が示す変位等高線に交わる方向に向かって延設される箇所を有すると良い。妻構体は、押出方向に剛性強化された押出形材を有して構成され、押出方向が幅方向と高さ方向との何れに対しても斜め方向である。他の押出形材の押出方向は妻構体の貫通路口の中心に集まる方向である。当該鉄道車両構体に負荷される荷重による妻構体における変位等高線を参照し、妻構体を構成する押出形材の一部、又は全ての押出方向を変位等高線に交わる方向に揃えることが好ましい。【選択図】 図2
