To provide a vehicular body structure in which a side collision load can be effectively dispersed and transmitted in a vehicle width direction in a vehicle having a step-lowering floor.SOLUTION: A second floor panel 42 between a floor upper frame 50 and a side sill 2 is formed at a position below a first floor panel 41 between the floor upper frame 50 and a floor tunnel 3. A frame top face part 50a of the floor upper frame 50 is provided at a position above a vertical direction center position P of an upper ridge part 25 and a lower ridge part 26 of the side sill 2. A first member 61 of a first cross 6 includes: a top face part 64 facing a floor panel 4; and a front face part 65 and a rear face part 66 that extend from both ends in the front-rear direction of the top face part 64 to the floor panel 4. The front face part 65 and the rear face part 66 are joined to the frame top face part 50a at a position above the vertical direction center position P of the upper ridge part 25 and the lower ridge part 26 of the side sill 2.SELECTED DRAWING: Figure 3

    【課題】段下げフロアを有する車両において側突荷重を車幅方向に有効に分散伝達することができる車両の車体構造を提供する。【解決手段】フロアアッパフレーム50とサイドシル2との間の第2フロアパネル42はフロアアッパフレーム50とフロアトンネル3との間の第1フロアパネル41より低い位置に形成されている。フロアアッパフレーム50のフレーム上面部50aはサイドシル2の上側稜線部25と下側稜線部26との上下方向中心位置Pより高い位置に設けられている。第1クロスメンバ6の第1部材61は、フロアパネル4に対向する上面部64と、該上面部64の前後方向両端部からフロアパネル4に延びる前面部65及び後面部66とを備えている。前面部65及び後面部66は、サイドシル2の上側稜線部25と下側稜線部26との上下方向中心位置Pより高い位置でフレーム上面部50aに接合されている。【選択図】図3
