Abstract

The present disclosure relates to a vehicle underbody structure. On a side face of a floor tunnel (16), a side reinforcement (34) is disposed between a region at which a carriage front wall cross member (26) is connected to the floor tunnel and an upper edge of the side face. An upper reinforcement (22) extends in a longitudinal direction at an upper portion of the floor tunnel (16). The side reinforcement (34) extends rearward with its rear edge (34c) inclining upward. A collision load (F1) input from a side member (32) enters the side face of the floor tunnel (16) via the carriage front wall cross member (26). The collision load (F3), which is transmitted on the floor tunnel (16), is transmitted to the upper reinforcement (22) along the rear edge (34c) of the side reinforcement.
