Abstract

A vehicle-longitudinally extending front side member (1) has a rearwardly descending inclined portion (6) configured in an enclosure form in section with an upper wall (3) and a lower wall (4), the upper wall (3) being more rigid than the lower wall (4).

Description

technical field [0001] The present invention relates to the front structure of automobile body. Background technique [0002] The automobile body includes a pair of longitudinally extending front side members on the automobile, and a pair of longitudinally extending floor members on the automobile, the front side members are on the left and right sides of the vehicle transverse direction of the front compartment, and the floor members are located on the floor panel. ) on the car transverse left and right sides of the air duct (tunnel) portion, and the floor is arranged at the rear of the front compartment. Each front side member is connected to the corresponding floor member so that the latter is configured as an extension of the connected former via an inclined portion along the instrument panel between the front compartment and the floor (dashboard panel) outline and descending towards the rear. [0003] The impact of a crash can affect the front end of the front side me...
