To provide a vehicle bottom part structure that can improve absorption efficiency for an impact load at the time of a side collision.SOLUTION: A vehicle bottom part structure 1 includes: a rocker 20; a tunnel 21; a floor panel 22; a floor member 23; and a seat attachment member 24. The seat attachment member 24 is located above the floor panel 22 and includes an upper surface portion 50 extended from the rocker 20 inward in a vehicle width direction and a standing wall portion 51 extended from the upper surface portion 50 toward the floor panel 22 to be connected to the floor panel 22. The standing wall portion 51 is inclined inward in the vehicle width direction from the upper surface portion 50 toward a lower side in a vehicle up-down direction and is connected to a portion of the floor panel 22, which is located outward of the floor member 23 in the vehicle width direction.SELECTED DRAWING: Figure 3

    【課題】側突時の衝突荷重の吸収効率を向上することができる車両底部構造を提供する。【解決手段】車両底部構造1は、ロッカ20と、トンネル21と、フロアパネル22と、フロアメンバ23と、シート取付部材24と、を備える。シート取付部材24は、フロアパネル22の上方に位置し、ロッカ20から車両の幅方向の内側に向かって延設された上面部50と、上面部50からフロアパネル22に向かって延設し、フロアパネル22に接続された立壁部51と、を有する。立壁部51は、上面部50から車両の上下方向の下側に向かうにつれて車両の幅方向の内側に向かうように傾斜し、フロアパネル22におけるフロアメンバ23よりも車両の幅方向の外側の位置に接続されている。【選択図】図3
