The invention provides a lower vehicle body structure of a vehicle capable of suppressing deformation of a side member during a small overlap collision without increasing the weight and manufacturing cost of the side member, in which the side member (2) constituting the vehicle body is provided with an outer side member (11) and an inner side member (12). An upper side surface part (32A) (upper surface part) and a lower side surface part (32B) (lower surface part) of the inner side beam (12) are bent towards the inner side of the side beam (2) to form a second bent part (34) (bent part). An upper inclined surface section (36) and a lower inclined surface section (39) (inclined surface section), which incline in a direction in which the inner side member (12) widens in the vertical direction as the outer side member (11) approaches, and a second upper surface section (37) and a second lower surface section (40) (vehicle width direction surface section), which extend in the vehicle width direction from the second bent section (34) to the inside of the vehicle are provided.
本发明提供一种能够在不使侧梁的重量及制造成本增大的情况下抑制小重叠碰撞时的侧梁变形的车辆的下部车身结构,其中构成车身的侧梁(2)具备外侧梁(11)及内侧梁(12),内侧梁(12)的上侧侧面部(32A)(上表面部)及下侧侧面部(32B)(下表面部)通过向侧梁(2)的内侧弯折而形成第2弯折部(34)(弯折部),且具备:随着接近外侧梁(11)而向内侧梁(12)在上下方向扩宽的方向倾斜的上侧倾斜面部(36)及下侧倾斜面部(39)(倾斜面部)、从第2弯折部(34)向车内侧在车宽方向延伸的第2上表面部(37)及第2下表面部(40)(车宽方向面部)。
