To provide a lower vehicle body structure for a vehicle that is able to enhance the protection performance of a fuel tank more securely with a simple structure.SOLUTION: A fuel tank and a protective member disposed at a position facing one surface of the fuel tank intersecting a horizontal first direction are provided. The protective member includes: a pre-contact portion extending along a horizontal second direction orthogonal to the first direction, at least a part of which is disposed below the fuel tank; a pair of connecting portions respectively extending upward from both ends of the pre-contact portion in the second direction and having upper end parts coupled to a vehicle body; and a pair of reinforcing members connecting the pre-contact portion and each connecting portion in the vicinity of both ends of the pre-contact portion in the second direction. The reinforcing members are respectively joined to surfaces of the pre-contact portion and connecting portions, which surfaces are opposite to a surface facing the one surface of the fuel tank.SELECTED DRAWING: Figure 1

    【課題】簡単な構成で燃料タンクの保護性能がより確実に高められる車両の下部車体構造を提供する。【解決手段】燃料タンクと、水平な第1方向と交差する燃料タンクの一面と対向する位置に配設される保護部材とを設け、保護部材に、第1方向と直交する水平な第2方向に沿って延び且つ少なくとも一部が燃料タンクよりも下方に配置される先当て部と、先当て部の第2方向の両端からそれぞれ上方に延び且つ上端部が車体に結合される一対の連結部と、先当て部の前記第2方向の両端近傍において当該先当て部と各連結部とをそれぞれ連結する一対の補強部材とを設け、各補強部材を、先当て部と各連結部の、燃料タンクの前記一面と対向する面と反対側の面にそれぞれ接合する。【選択図】図1
