Zusammenfassung:	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
