VEHICLE UNDERBODY STRUCTURE

摘要

To obtain a vehicle body lower portion structure that can efficiently absorb and disperse load of a front or rear collision including an offset collision or an oblique collision, and transmit the load to an underbody. A vehicle body lower portion structure has an underbody (12) at which a dash lower portion (24) and a lower back portion (26) are provided to stand from both ends in a vehicle front-rear direction at a floor portion (22), a suspension member (50) the length direction thereof is along a vehicle transverse direction and is joined to the underbody (12) in a state of planarly-contacting a front surface of the dash lower portion (24), and a front EA member (16) a length direction thereof is along the vehicle transverse direction and is joined to a front wall (50F) of the suspension member (50).
