To provide a vehicle body substructure capable of inhibiting transmission of a vibration from a lower part of a vehicle body to an upper part of the vehicle body.SOLUTION: The lateral parts of a vehicle body substructure 11 include a pair of locker members 12a and 12b respectively and a pair of side member outer members 13a and 13b respectively. At least one of the lateral parts of the vehicle body substructure 11 has a joint structure in which the locker member 12a is joined to the side member outer member 13a with a first adhesive 71 and the locker member 12a is joined to a main floor member 21 with a second adhesive 72 different from the first adhesive 71. The storage modulus E1 of the first adhesive 71 and the storage modulus E2 of the second adhesive 72 have a relationship of E1>E2.SELECTED DRAWING: Figure 2
【課題】車体下部から車体上部への振動伝達を抑えることのできる車体下部構造を提供する。【解決手段】車体下部構造11の両側部は、一対のロッカー部材12a,12bと、一対のサイドメンバアウター部材13a,13bとを備える。車体下部構造11の両側部のうち、少なくとも一方の側部は、ロッカー部材12aとサイドメンバアウター部材13aとが第1接着剤71により接合され、かつロッカー部材12aとメインフロア部材21とが第1接着剤71とは異なる第2接着剤72により接合された接合構造を有する。第1接着剤71の貯蔵弾性率E1と、第2接着剤72の貯蔵弾性率E2とは、E1>E2の関係を満たす。【選択図】図2
