To provide a railway vehicle body structure whose column member bends and deforms enough when an obstacle collides with the column member in the condition a railway vehicle body structure comprises the column member extending toward a roof structure from an end beam located at the underframe end in the longitudinal direction of the vehicle.SOLUTION: A railway vehicle body structure comprises a column member extending toward a roof structure from an end beam which is located at an underframe end in the longitudinal direction of the vehicle and the column member comprises a junction bonded to the end beam or the roof structure and a hinge part which is located on an inner side face of the body, between the junction and the column center in vertical direction and not only starts bending deformation but also functions as an origin of bending deformation before breakage of the junction when a load more than a prescribed quantity is applied.SELECTED DRAWING: Figure 1 【課題】台枠の車両長手方向端部に位置する端梁から屋根構体に向けて延びる柱部材を備えた鉄道車両構体において、障害物が柱部材に衝突した際に柱部材が十分に曲げ変形できる構成を提供する。【解決手段】台枠の車両長手方向端部に位置する端梁から屋根構体に向けて延びる柱部材を備えた鉄道車両の構体であって、前記柱部材は、前記端梁又は前記屋根構体と接合される接合部と、前記接合部から前記柱部材の鉛直方向中心位置までの間であって、その車内側の面に位置し、所定以上の荷重が付加されると、前記接合部が破断する前に曲げ変形を開始するとともに、その曲げ変形の起点となるヒンジ部と、を備える。【選択図】図１
