To provide a vehicle body for a railroad vehicle that can appropriately reduce low-frequency pressure variation when the railroad vehicle travels.SOLUTION: The vehicle body for a railroad vehicle comprises a bottom part-closing plate extending horizontally opposing to a ground surface at one side in a vehicle longitudinal direction of a bogie, and an end part-closing plate extending upward from the bottom part-closing plate in a proximal side of the bogie to oppose in the vehicle longitudinal direction to the bogie. The end part-closing plate has an inclined surface inclined so as to approach the bogie as going upward from the bottom part-closing plate, and a perpendicular surface perpendicular to the vehicle longitudinal direction, which opposes in the vehicle longitudinal direction to an upper part of the bogie. The inclined surface includes a convex surface part having a curved shape, connected to an end part of the bottom part-closing plate in the proximal side of the bogie, in which inclinations of a tangent line of a cross section perpendicular to a vehicle width direction gradually increase as approaching the bogie, and a concave surface part having a curved shape, arranged closer to the proximal side of the bogie than the convex surface part, in which inclinations of a tangent line of the cross section perpendicular to the vehicle width direction gradually decrease as approaching the bogie.SELECTED DRAWING: Figure 2

    【課題】鉄道車両が走行する際の低周波圧力変動を好適に低減することができる鉄道車両用車体を提供する。【解決手段】鉄道車両用車体は、台車の車両長手方向一方側で地面に対向して水平に延びる底部塞ぎ板と、台車の近位側における底部塞ぎ板の端部から上方に延びて、台車に車両長手方向に対向する端部塞ぎ板と、を備え、端部塞ぎ板は、底部塞ぎ板から上方にいくにつれて台車に近づくように傾斜した傾斜面と、前記傾斜面の上側端部から上方に延び、前記台車の上部に車両長手方向に対向する、車両長手方向に対して垂直な垂直面とを有し、傾斜面は、台車の近位側における底部塞ぎ板の端部につながり、車幅方向に垂直な断面の接線の傾きが台車に近づくにつれ徐々に上昇する湾曲形状を呈する凸面部と、凸面部よりも台車の近位側に配置され、車幅方向に垂直な断面の接線の傾きが台車に近づくにつれ徐々に減少する湾曲形状を呈する凹面部と、を含む。【選択図】図2
