To provide a lower vehicle-body structure of a vehicle which can properly increase the bending resistance of a side sill without increasing its weight and manufacturing costs.SOLUTION: A side sill 2 constituting a vehicle, comprises a side sill outer 11 and a side sill inner 12. Each of an upper-side side face portion 22A (upper face portion) and a lower-side side face portion 22B (lower face portion) of the side sill outer 11 comprises a first bending portion bent 24 toward an inside of the side sill 2. The side sill inner 12 comprises: an upper-side side face portion 32A provided with a series of a first upper face portion 35, an upper-side slant face portion 36 and a second upper face portion 37, which are aligned in a vehicle width direction Y, and a lower-side side face portion 32B provided with a series of a first lower face portion 38, a lower-side slant face portion 39 and a second lower face portion 40, which are aligned in the vehicle width direction Y. The side sill inner 12 comprises a pair of upper-and-lower second bending portions 34 which are bent toward an inside of the side sill 2 at respective positions between the second upper face portion 36 and the upper-side slant face portion 37 and between the second lower face portion 40 and the lower-side slant face portion 39.SELECTED DRAWING: Figure 5
【課題】サイドシルの重量および製造コストを増大させずにサイドシルの曲げ耐力を増大させることが可能な車両の下部車体構造を提供する。【解決手段】車体を構成するサイドシル2は、サイドシルアウタ11およびサイドシルインナ12を備える。サイドシルアウタ11の上側側面部22A(上面部)および下側側面部22B(下面部)は、サイドシル2の内側に折れ曲がる第1折曲部24を備える。サイドシルインナ12は、車幅方向Yに並ぶ一連の第1上面部35、上側傾斜面部36、および第2上面部37を備える上側側面部32Aと、車幅方向Yに並ぶ一連の第1下面部38、下側傾斜面部39、第2下面部40を備える下側側面部32Bとを備える。さらに、サイドシルインナ12は、第2上面部36と上側傾斜面部37との間、および、第2下面部40と下側傾斜面部39との間にサイドシル2の内側に折れ曲がる上下一対の第2折曲部34を有する。【選択図】図5
