To make deformation of a floor structure of a vehicle less likely to occur.SOLUTION: A floor structure of a vehicle 1 has first reinforcement members 40 and second reinforcement members 50 provided in areas enclosed by first cross members 17, side sills 11, a second cross member 15, and center skeleton members 13 forming a vehicle body 2. One side surface 47 of a first triangle structure part 44 of the first reinforcement member 40 is provided near the first cross member 17 so as to extend along the first cross member 17. The other side surface 48 of the first triangle structure part 44 is provided so as to extend along a diagonal bracing direction 28 from a front outer connection portion 26 between the side sill 11 and the first cross member 17 to a rear middle connection portion 27 between the center skeleton member 13 and the second cross member 15. The second reinforcement member 50 has a three-dimensional structure part extending at least from the rear middle connection portion 27 in a direction of the front outer connection portion 26. The first reinforcement member 40 and the second reinforcement member 50 are separated from each other in the diagonal bracing direction 28.SELECTED DRAWING: Figure 6

    【課題】車両のフロア構造の変形が生じ難くなるようにする。【解決手段】車両1のフロア構造は、車体2を構成する第一クロスメンバ17、サイドシル11、第二クロスメンバ15、および中央骨格部材13に囲われる領域に設けられる第一補強部材40および第二補強部材50を有する。第一補強部材40の第一の三角体構造部44の一側面47が、第一クロスメンバ17に沿って延在するように第一クロスメンバ17の近くに設けられる。第一の三角体構造部44の他の一側面48が、サイドシル11と第一クロスメンバ17との前外連結部分26から中央骨格部材13と第二クロスメンバ15との後中連結部分27へ向かう筋交い方向28に沿って延在するように設けられる。第二補強部材50は、少なくとも後中連結部分27から前外連結部分26の方向へ向けて延在する立体構造部を有する。第一補強部材40と第二補強部材50とは、筋交い方向28において離間している。【選択図】図6
