Abstract

A vehicle body front structure (10) having: a shock absorbing portion (31) forming a front portion of a front side frame (11); and a beam support provided on an inner side wall (43) of the shock absorbing portion (31) Parts (22). The impact absorbing portion (31) is compressively deformable, and the strength of the inner wall (43) is set higher than that of the outer wall (51). A beam support member (22) is formed so as to be able to face the front bumper beam (18). The cross-sectional shape of the front bumper beam (18) is formed so as to increase from the left end portion (18a) toward the center in the vehicle width direction.

Description

technical field [0001] The present invention relates to a vehicle body front structure in which left and right front frames are provided at predetermined intervals in the vehicle width direction, and a front bumper beam is bridged over front ends of the left and right front frames. Background technique [0002] As disclosed in Patent Document 1, for example, in the structure of the front part of the vehicle body, there is known a structure in which crash boxes protrude from the front ends of the left and right front side frames respectively, and crash boxes are mounted on the front ends of the left and right crash boxes. Bumper beam. In this vehicle body front structure, a substantially L-shaped load bearing member is connected to the front end portion of the crash box and the vicinity of the end portion of the front bumper beam. [0003] The load bearing member has a convex corner because it is formed in a substantially L-shape, one end of the load bearing member is provid...
