Abstract

A structure for the front of a vehicle body. Said structure comprises the following: left and right front-side frames (12, 12) that are located at the front of a vehicle body (11) and extend in the longitudinal direction thereof; a front bulkhead (13) provided between the front ends of said left and right front-side frames; and a bumper (14) laid out in front of said front bulkhead. Left and right side bulkhead members (22, 22) on the front bulkhead comprise left and right front walls (22a, 22a) and left and right rear walls (22b, 22b) located behind said left and right front walls at a distance therefrom. The abovementioned bumper overlaps the front surfaces of the aforementioned left and right front walls. Left and right stays (40, 40) extend between the left and right front walls and the left and right rear walls. The front ends of said left and right stays, the left and right front walls, and the bumper are joined together. The rear ends of the left and right stays are joined to the left and right rear walls.

Description

technical field [0001] The present invention relates to a technique for improving a dash panel and its surroundings in a front portion of a vehicle body in a vehicle such as a passenger car. Background technique [0002] A vehicle such as a passenger car has a dash panel at the front of the vehicle body. A bumper is arranged in front of the front bulkhead. Such a vehicle body front structure is known from Patent Document 1.
