This vehicle body lower structure for an automobile is provided with a specific constituent member including a side member (1) having a structure in which a closed cross-sectional space (3) is partitioned into two closed cross-sectional spaces (3a, 3b) by a partition member (2) in the vehicle width direction. The side member has an impact absorbing structure (A) comprising: a pair of groove-shaped cross-section members (4a, 4b) that are joined to the partition member (2) in the closed cross-section spaces (3a, 3b) in a state in which the partition member (2) is sandwiched from both sides, and that respectively form closed cross-section spaces (5a, 5b) with the partition member (2); and partitions (6) that partition the closed cross-sectional spaces (5a, 5b) by being provided within the closed cross-sectional spaces (5a, 5b) in the vehicle width direction. Partition plates (6) in the closed cross-sectional spaces (5a, 5b) are provided under predetermined arrangement conditions, and each partition plate (6) is joined to at least the groove-shaped cross-sectional members (4a, 4b).

    本发明的汽车的车体下部结构是具备包括侧梁(1)的特定的构成构件的汽车的车体下部结构,侧梁(1)具有闭合截面空间(3)在车辆宽度方向上由分隔构件(2)分隔为两个闭合截面空间(3a、3b)的结构,并且侧梁具有由一对槽形截面构件(4a、4b)和隔板(6)构成的冲击吸收结构体(A),所述一对槽形截面构件(4a、4b)在闭合截面空间(3a、3b)内在从两侧夹着分隔构件(2)的状态下与分隔构件(2)接合且在与分隔构件(2)之间分别形成闭合截面空间(5a、5b),所述隔板(6)通过沿着车辆宽度方向设置在各闭合截面空间(5a、5b)内从而分隔闭合截面空间(5a、5b)。闭合截面空间(5a、5b)内的隔板(6)以规定的配置条件设置,各隔板(6)至少与槽形截面构件(4a、4b)接合。
