VEHICLE BODY STRUCTURE

To achieve reduction of an internal stress which is generated due to a thermal expansion coefficient difference in a vehicle body members as joining objects when joining the vehicle body members comprising dissimilar metals.SOLUTION: A vehicle body structure, in which a terminal part 23 in a prescribed direction of a first vehicle body member 2 comprising a first metal is joined to a second vehicle body member 4 comprising a second metal, comprises a third vehicle body member 5 which comprises the first metal, and is interposed between the first vehicle body member 2 and the second vehicle body member. The third vehicle body member 5 has: a general part 53 which is positioned near the second vehicle body member 4, and is crimped to the second vehicle body member 4; and a base part 54 which is adjacent to the general part 53, is positioned near the first vehicle body member 2, and is weld-joined to the first vehicle body member 1. The general part 53 has a notch part 53b on a side opposite to a welded joint 54a with respect to a crimped part 53a.SELECTED DRAWING: Figure 7 【課題】異種金属からなる車体部材同士を接合する際に、接合対象となる車体部材において熱膨張率差に起因して生じる内部応力の低減を図る。【解決手段】第１金属からなる第１車体部材２の所定方向の端末部２３が、第２金属からなる第２車体部材４へ接合される車体構造であって、第１金属からなり、第１車体部材２と第２車体部材の間に介在する第３車体部材５を備え、第３車体部材５は、第２車体部材４寄りに位置して第２車体部材４とかしめ結合される一般部５３と、一般部５３と隣接し第１車体部材２寄りに位置して第１車体部材１と溶接接合される台部５４と、を有し、一般部５３は、かしめ結合部５３ａについて溶接接合部５４ａと反対側に切欠部５３ｂを有する。【選択図】図７
