PROBLEM TO BE SOLVED: To provide a rail vehicle body structure for reducing strain of a joining part between a single skin section and a frame, and capable of also securing rigidity and strength of the whole body structure.SOLUTION: In a rail vehicle body structure composed by combining a roof body structure, a side body structure, an underframe and a gable end body structure, the roof body structure, the side body structure, the underframe and the gable end body structure, are respectively formed of a light alloy single skin with a T-shaped rib and a light alloy frame, and are provided by executing frictional agitation joining of the single skin with a horizontal flange of the frame at a position of a longitudinal rib of the T-shaped rib, in joining of the light alloy single skin with the T-shaped rib and the light alloy frame.

    【課題】シングルスキン形材とフレームとの接合部の歪を低減し、かつ、構体全体の剛性及び強度を確保できる軌条車両構体を提供すること。【解決の手段】前記目的は、屋根構体、側構体、台枠及び妻構体を組合せて構成される軌条車両構体において、屋根構体、側構体、台枠及び妻構体をそれぞれ軽合金製T字型リブ付シングルスキンと軽合金製フレームで構成し、前記軽合金製T字型リブ付シングルスキンと軽合金製フレームの結合において、T字型リブの縦リブの位置でフレームの水平フランジと摩擦撹拌接合したことにより達成される。【選択図】図6
