PROBLEM TO BE SOLVED: To enable whole connection beams to be firmly joined to a pair of arms extending in the vehicle body longitudinal direction by welding, when adopting vehicle body support structure in which the pair of arms are joined by the plurality of connection beams.SOLUTION: A vehicle body support structure 10 according to the present invention comprises a pair of arms 11 and 12 extending in the vehicle body longitudinal direction and at least two connection beams for connecting the pair of arms 11 and 12 to each other. The arm 11 comprises a first divided arm part 16 having a wall part 18 on the inside in the vehicle width direction and a second divided arm part 17 having a wall part 19 on the outside in the vehicle width direction. Among at least the two connection beams, both first and second connection beams 14 and 15 are joined by welding to the wall part 18 of the one divided arm part 16, and a first welded portion 33 is also formed between the first connection beam 14 and a surface 18a directing the vehicle width direction-inside of the wall part 18, and a second welded portion 34 is formed between the second beam part 15 and a surface 18b directing the vehicle width direction- outside of the wall part 18.SELECTED DRAWING: Figure 1
【課題】複数の連結ビームで車体前後方向に伸びる一対のアームを連結してなる車体支持構造をとる場合に、全ての連結ビームを一対のアームに対して溶接により強固に接合可能とする。【解決手段】本発明に係る車体支持構造10は、車体前後方向に伸びる一対のアーム11,12と、一対のアーム11,12を相互に連結する少なくとも二本の連結ビームとを備える。アーム11は、車幅方向内側の壁部18を有する第一の分割アーム部16と、車幅方向外側の壁部19を有する第二の分割アーム部17とを有する。少なくとも二本の連結ビームのうち第一及び第二の連結ビーム14,15はともに一方の分割アーム部16の壁部18に溶接で接合されており、かつ第一の連結ビーム14と、壁部18の車幅方向内側を指向する面18aとの間に第一の溶接部33が形成され、第二の連結ビーム15と、壁部18の車幅方向外側を指向する面18bとの間に第二の溶接部34が形成されている。【選択図】図1
