VEHICLE UNDER STRUCTURE

The present invention provides a vehicle lower structure capable of suppressing deformation of a lower dash panel toward the indoor side. A vehicle lower structure is provided with: a floor panel (2) provided between a floor tunnel (1) and a side sill (3); and a front pillar (4) extending in the vertical direction of the vehicle from the front end (3a) of the side sill (3). A vehicle lower structure is provided with a lower dash panel (7) disposed on the front side (2a) of a floor panel (2), and a lower dash panel cross member (8) extending in the vehicle width direction on the lower end side of the lower dash panel (7). The inner end (14) of the lower dash cross member (8) in the vehicle width direction is connected to the floor tunnel (1), and the outer end (15) of the lower dash cross member (8) in the vehicle width direction is connected to the front pillar (4). 本发明提供能够抑制下前围板向室内侧变形的车辆下部构造。车辆下部构造包括：底板(2)，其张设在地板通道(1)与下纵梁(3)之间；以及前柱(4)，其从下纵梁(3)的前端部(3a)沿车辆上下方向延伸。车辆下部构造包括配置在底板(2)的前侧(2a)的下前围板(7)和在下前围板(7)的下端侧沿车宽方
