Problems solved by technology

[0004] However, in the underbody structure described in JP-A-2007-131148, the floor member and reinforcement are provided for the front side members, thus increasing the bending rigidity of the front portion of the front side members
Therefore, in order to increase the rigidity of the front portion of the main frame such as the front side member (floor member), the number of parts increases

Abstract

A floor member (1) includes a floor member front (11 ) arranged at a front side and a floor member rear (12) arranged at a rear side. A member rear upper (13) is mounted on the floor member front (11). The floor member front (11) and the floor member rear (12) respectively have a front upper bead (14) and a rear lower bead (15) that extend in a longitudinal direction of a vehicle.

Description

technical field [0001] The present invention relates to a lower structure of a vehicle, and more particularly to a lower structure of a vehicle including a joint between a floor and a main frame extending in the longitudinal direction of the vehicle. Background technique [0002] The substructure of a vehicle needs to absorb the loads applied in the event of a vehicle crash. As a load-absorbing structure, for example, Japanese Patent Application Laid-Open No. 2007-131148 (JP-A-2007-131148) describes a vehicle body underbody structure. In this vehicle body understructure, a floor is coupled to an upper portion of a front side member, and a floor upper member is provided at a turn-up portion, thus providing reinforcement inside the front side member. [0003] In this vehicle body substructure, the upper floor member is disposed above the front side members and provides reinforcement inside the front side members. Therefore, the upper vehicle body substructure can improve pro...
