The invention provides a vehicle body lower portion structure which can improve air mechanical performance and can restrain impact on a guide plate when the guide plate encounters an obstacle. The vehicle body lower structure includes: a deflector provided on a vehicle body of a vehicle and movable between a stowed position covering a lower portion of the vehicle body and a deployed position protruding downward; and a shaft member extending in the left-right direction of the vehicle and rotatably connecting the front end of the deflector to the vehicle body, in which the deflector is maintained at the deployed position protruding downward due to its own weight, and when subjected to an impact load from below, the deflector is held at the deployed position protruding downward. And the guide plate moves from the unfolding position to the storage position.

    本发明提供一种车体下部结构,能够提升空气力学性能,且能够抑制导流板在遇到障碍物时所受到的冲击。车体下部结构包括:导流板,设置在车辆的车体上、且能够在覆盖所述车体的下部的收纳位置以及往下方突出的展开位置之间移动;以及轴部件,在车辆左右方向上延伸,将所述导流板的前端可旋转地连接在所述车体上,其中,所述导流板经由自重而维持在往下方突出的所述展开位置,并且,在受到来自下方的冲击负载的情况下,所述导流板从所述展开位置往所述收纳位置移动。
