Abstract

The present disclosure relates to a lower body structure of a vehicle. A side reinforcement (34) is arranged between the area of ​​the side of the floor tunnel (16) where the front compartment front wall cross member (26) is joined and the upper edge of the side. An upper reinforcement (22) extending in the longitudinal direction is arranged above the floor tunnel (16). The rear edge (34c) of the side reinforcement (34) extends toward the rear, and is inclined so as to rise in the rear. The crash load (F1) input from the side member (32) is input to the side of the floor tunnel (16) via the cabin front wall cross member (26). Also, the impact load (F3) transmitted on the floor tunnel (16) is transmitted along the rear edge (34c) of the side reinforcement, thereby being transmitted to the upper reinforcement (22).

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims priority from Japanese Patent Application No. 2018-121797 filed on Jun. 27, 2018, which is hereby incorporated by reference in its entirety, including the specification, claims, drawings of the specification, and abstract of the specification . technical field [0003] The present disclosure relates to a lower body structure of a vehicle, and more particularly, to a structure for ensuring strength in a collision. Background technique [0004] In the following Patent Document 1, a structure for reinforcing a floor tunnel extending front and rear at the center of the floor of the vehicle is shown. The impact load input to the front part (35A) of the floor tunnel is transmitted to the tunnel lower stiffener (32) via the tunnel upper stiffener (40). Additionally, input from the front side member (68) is input to the tunnel lower stiffener (32) via the inner torque box (88). In addition, the symbol...
