To provide a railway vehicle body structure which has an improved strength of a joint between a gable end structure and a roof structure in a collision.SOLUTION: A railway vehicle body structure 1 comprises a gable end structure 4 and a roof structure 6 which are bonded mutually and a rafter member 10 which enforces the roof structure 6 at a lower part of the roof structure 6. The gable end structure 4 has a gable end structure joint surface 4p which expands vertically and parallelly with the gable end structure and the roof structure 6 has a roof structure joint surface 6p which expands vertically and parallelly with the gable end structure. The gable end structure joint surface 4p and the roof structure joint surface 6p are mutually jointed through a rafter member joint part 11 which is integrated with the rafter member 10 and extends upward from the rafter member 10. Therefore, the strength of the roof structure 6 is improved by the rafter member 10 and in a general collision in a cross direction, a force to peel the roof structure 6 from the gable end structure 4 is hardly generated because the gable end structure joint surface 4p of the gable end structure 4 and the roof structure joint surface 6p of the roof structure 6 are vertically parallel with each other. Then, peeling of the roof structure 6 from the gable end structure 4 in a collision is weakened and the strength in a collision is elevated.SELECTED DRAWING: Figure 3
【課題】衝突時における妻構体と屋根構体との接合の強度が向上する鉄道車両構体を提供する。【解決手段】妻構体4及び屋根構体6を接合してなる鉄道車両構体1において、屋根構体6の下方で屋根構体6を補強する垂木部材10を備え、妻構体4は、上下方向に平行な妻構体接合面4pを有し、屋根構体6は、上下方向に平行な屋根構体接合面6pを有し、妻構体接合面4pと屋根構体接合面6pとが、垂木部材10と一体化しつつ垂木部材10から上方に延在する垂木部材接合部11を介して、互いに接合されている。このため、垂木部材10により屋根構体6の強度が向上するとともに、妻構体4の妻構体接合面4pと屋根構体6の屋根構体接合面6pとは上下方向に平行であるため、一般的な前後方向からの衝突時に妻構体4から屋根構体6を剥離させる力が働き難い。そのため、衝突時における妻構体4からの屋根構体6の剥離が低減し、衝突時における強度が向上する。【選択図】図3
