To provide a thin structural member which contributes to the improvement of assemblability of a vehicle body, is light-weight and has high rigidity, and a railroad vehicle that forms a floor surface with an underframe structure with such a structural member.SOLUTION: A body bolster of a railroad vehicle includes: a plurality of radial ribs arranged radially from the center of a vertical load input unit and having a shape of a protrusion on the surface of a flat plate arranged horizontally with a curvature provided in the longitudinal or width direction of a vehicle more gently as it moves away from the center of the vertical load input unit; and a circular rib arranged intermittently around a vertical load input seating surface so as to overlap the plurality of radial ribs.SELECTED DRAWING: Figure 4
【課題】車体の組立性向上に寄与するとともに軽量かつ剛性の高い薄型の構造部材、およびこのような構造部材を備えた台枠構造で床面を構成する鉄道車両を提供する。【解決手段】鉄道車両の枕梁は、垂直荷重入力部の中心から放射状に配置され、水平方向に配置された平板の面上に突起状の形状を有し、垂直荷重入力部の中心から離れるに従って緩やかに車両の長手方向もしくは幅方向に沿うように曲率が設けられた複数の放射状リブと、複数の放射状リブに重なるように垂直荷重入力座面の周辺に、断続的に配置された円形リブと、を有する。【選択図】 図4
