    • A vehicle lower section structure is obtained that has a simple structure and is capable of increasing the rigidity and strength of a framework structure that is long in the vehicle front-rear direction. A vehicle lower section structure includes: an upper panel including a pair of respectively vehicle-downwards facing joining faces that are separated from each other in the vehicle width direction; a lower panel that with the upper panel configures a framework structure that is long in the vehicle front-rear direction and has a closed cross-section by the joining faces of the upper panel being joined to vehicle-upwards facing joining faces of the lower panel; and a seat rail that is long in the vehicle front-rear direction and is fixed to a portion of the upper panel that configures an upper wall of the closed cross-section of the framework structure.
    • 获得具有简单结构并且能够增加在车辆前后方向上长的框架结构的刚性和强度的车辆下部结构。 车辆下部结构包括:上部面板,其包括在车辆宽度方向上彼此分离的一对分别车辆向下的接合面; 具有上板的下板构成了车辆前后方向长的框架结构,并且通过上板的接合面被连接到下板的车对面的接合面而具有闭合的横截面 ; 以及座椅导轨,其在车辆前后方向上长并且固定到构成框架结构的封闭横截面的上壁的上板的一部分。
