The present invention provides a vehicle body lower structure capable of suppressing deformation of a battery housing part caused by a collision load inputted by a collision in the front-rear direction of a vehicle without reinforcing the battery housing part by a reinforcing member, for example. A vehicle body lower structure (10) is provided with a front cross member (14), a rear frame (13), a floor panel (22), and a front floor panel frame (23). The front cross member (14) is disposed in front of the battery (121) in the vehicle. The rear frame (13) is connected to an outer end (14B) of the front cross member (14) in the vehicle width direction. The front floor frame (23) forms a closed cross-section together with the floor panel (22), and is connected to the outer end of the front cross member (14) in the vehicle width direction.
本发明提供一种例如不通过加强构件对蓄电池收容部进行加强,就能够抑制因车辆前后方向的碰撞而输入的碰撞载荷引起的蓄电池收容部的变形的车身下部结构。车身下部结构(10)具备前横梁(14)、后侧框架(13)、底板(22)及前底板框架(23)。前横梁(14)配置在蓄电池(121)的车辆前方。后侧框架(13)与前横梁(14)的车宽方向外侧端部(14B)连接。前底板框架(23)与底板(22)一起形成闭合截面,并与前横梁(14)的车宽方向外侧端部连结。
