To prevent an edge of an inner flange part disposed on a lower side frame from interfering with a fuel tank upon occurrence of side collision.SOLUTION: A lower body structure of a vehicle comprises: a floor 5, left and right lower side frame lowers 62 joined to an under-surface of the floor 5 and constituting a closed section 60s extending in a vehicle longitudinal direction at a space between themselves and the undersurface of the floor 5, and a fuel tank 9 disposed on the underside of the floor 5 and between the left and right lower side frame lowers 62. In the lower body structure of a vehicle, an easy-to-deform part 55 to be deformed more downward from the inner flange part 62a during side collision is formed at a position adjacent, inside in a vehicle width direction, to an inner flange part 62a extending inward in the vehicle width direction at an inner end of the lower side frame lower 62 in the vehicle width direction in the floor 5 and overlapping with the fuel tank 9 in a vehicle side view.SELECTED DRAWING: Figure 1

    【課題】側突時にサイドフレームロアに備えた内側フランジ部のエッジが燃料タンクに干渉することを防ぐこと。【解決手段】フロア5と、該フロア5の下面に接合されるとともに該フロア5の下面との間に車両前後方向に延びる閉断面60sを構成する左右のサイドフレームロア62と、フロア5の下方、かつ、左右のサイドフレームロア62間に配設される燃料タンク9を備える車両の下部車体構造であって、フロア5における、サイドフレームロア62の車幅方向内端にて車幅方向内方へ延出する内側フランジ部62aに対して車幅方向内側で隣接するとともに車両側面視で燃料タンク9と重なる位置に、側突時に内側フランジ部62aよりも下方に向けて変形する易変形部55を形成した。【選択図】図1
