To inhibit twisting caused when a side collision load generated by a pole collision is input to reduce deformation to the compartment inner side.SOLUTION: Each floor flame 16 has a second extending member 28 in a closed cross section formed with a floor part 12. The second extending member extends from a first cross member 22 to a second cross member 24 along a vehicle fore and aft direction and is provided so that a vertical section area of a closed cross section formed by the second extending member 28 and the floor frame 16 becomes larger toward the vehicle front. An outrigger 20 is disposed at the rear relative to a center of the second extending member.SELECTED DRAWING: Figure 1

    【課題】ポール衝突による側突荷重の入力時に発生する捩れを抑制して、室内側への変形量を低減すること。【解決手段】各フロアフレーム16は、フロア部12との閉断面内において第2延出部材28を有し、この第2延出部材は、車両前後方向に沿って第1クロスメンバ22から第2クロスメンバ24まで延出すると共に、車両前方に向かうにつれて第2延出部材28とフロアフレーム16との間で構成される閉断面の縦断面積が大きくなるように設けられ、アウトリガ20は、第2延出部材の中央よりも後方側に配置されている【選択図】図1
