To obtain reaction force in a vehicle width direction by suppressing a front end part of a side sill from being crushed by an inward impact load in a vehicle width direction inputted to the front end part of the side sill at the time of small overlap collision.SOLUTION: A lower vehicle body structure of a vehicle comprises: a side sill 10, arranged at a lower part of the vehicle and outside in a vehicle width direction, in which a closed cross section 10s extending in a longitudinal direction of the vehicle is formed by a side sill inner 11 and a side sill outer 21 in cooperation; a wheel 6 positioned in front of the side sill outer 21; an outer-side reinforcement member 50 having a shape formed along a front surface part 271 in the front end part 27 of the side sill outer 21 and a side surface part 24 and is joined to the front end part 27 from inside of the closed cross section 10s; and an inner-side reinforcement member 60 through which the front surface part 171 in the front end part 17 of the side sill inner 11 and the side surface part 14 are connected in a brace-shape.SELECTED DRAWING: Figure 5

    【課題】スモールオーバーラップ衝突時にサイドシル前端部に入力される車幅方向内向きの衝撃荷重に対して該サイドシル前端部のつぶれを抑制して車幅方向反力を得ること。【解決手段】車両の下部且つ車幅方向外側に配置され、サイドシルインナ11とサイドシルアウタ21とが協働して車両前後方向に延びる閉断面10sを形成するサイドシル10と、サイドシルアウタ21の前方に位置するホイール6と、サイドシルアウタ21の前端部27における前面部271および側面部24に沿った形状を有するとともに、閉断面10sの内側から前端部27に接合されたアウタ側補強部材50と、サイドシルインナ11の前端部17における前面部171と側面部14との間を筋交い状に連結するインナ側補強部材60とを備えた。【選択図】図5
