To provide a vehicle substructure that can suppress deformation of a frame member while protecting an on-vehicle member.SOLUTION: A vehicle substructure is provided with: a protective member 40 which is located below a frame member 2 so as to face an on-vehicle member 6 from an outer side in a vehicle width direction; and support members 50, 60 which are fixed to an undersurface of the frame member 2 and support the protective member 40. The support members 50, 60 are provided with: a bottom wall part 61 which includes an opposing part 61A facing an upper end part 43A of the protective member 40 in a vertical direction, and extends along an undersurface 2F of the frame member 2; and a vertical wall part 6 which extends downward with an inside edge of the bottom wall part 61 in the vehicle width direction as a base end. The vertical wall part 62 is provided with: a curved part 62C which curves so as to evaginate inward in the vehicle width direction; and an extension part 62D which extends to a tip side from the curved part 62C, and is positioned on an outer side in the vehicle width direction with respect to the curved part 62C.SELECTED DRAWING: Figure 3
【課題】車載部材を保護しつつフレーム部材の変形を抑制できる車両の下部構造を提供する。【解決手段】車載部材6に対し車幅方向の外側から対向するようにフレーム部材2の下方に配置された保護部材40と、フレーム部材2の下面に固定されて、保護部材40を支持する支持部材50,60とを設ける。支持部材50,60に、保護部材40の上端部43Aと上下方向に対向する対向部61Aを含み且つフレーム部材2の下面2Fに沿って延びる底壁部61と、当該底壁部61の車幅方向の内側縁を基端として下向きに延びる縦壁部6とを設け、縦壁部62に、車幅方向の内側に膨出するように湾曲する湾曲部62Cと、湾曲部62Cから先端側に延びるとともに湾曲部62Cよりも車幅方向の外側に位置する延長部62Dとを設ける。【選択図】図3
