To provide a railway vehicle body structure which can secure joint strength of welding and inhibit heat input in an internal fitting structure.SOLUTION: A railway vehicle body structure includes: an outer panel 10 provided with a door opening; a side beam 30 disposed at the inner side of the outer panel 10; and a door frame 20 disposed between the outer panel 10 and the side beam 30 at a position corresponding to the door opening. The door frame 20 has a thick body part 23 and a thin part 24 which is thinner than the body part 23. The door frame 20 is welded to the outer panel 10 and the side beam 30 at the thin part 24.SELECTED DRAWING: Figure 7

    【課題】内嵌め構造において溶接の接合強度の確保と入熱の抑制とを両立できる鉄道車両構体を提供する。【解決手段】鉄道車両構体は、ドア用開口部が設けられた外板10と、外板10の内側に配置された側梁30と、ドア用開口部に対応する位置で外板10と側梁30との間に配置されたドアフレーム20と、を備える。ドアフレーム20は、厚肉の本体部23と、本体部23よりも薄い薄肉部24と、を有する。ドアフレーム20は、薄肉部24において外板10及び側梁30に溶接されている。【選択図】図7
