Abstract

In order to increase tension rod support rigidity and sub crush can attachment rigidity, while forming a front sub-frame front section using a plate material, the present invention has a configurationwhereby: a sub crush can attachment section (12) and a tension rod support section (14) are provided in a front section of a front sub frame (5); a front-side vehicle body attachment section (13) isprovided between both; a suspension cross member (73) is provided in the front-side vehicle body attachment section (13) and the tension rod support section (14); the front-side vehicle body attachment section (13) comprises a sub crush can weight transfer member (30); and an upper surface section (21) of the front-side vehicle body attachment section (13) and a partition (33) in the sub crush canweight transfer member (30) extend in the vehicle front / rear direction, separated from each other.

Description

technical field [0001] The technology disclosed in this specification relates to a front subframe structure arranged under a front side member. Background technique [0002] Heretofore, a well-known front subframe has a sub-crash can mounting portion, a tie rod support portion, and a cross member extending in the vehicle width direction so as to face the tie rod support portion from the inside in the vehicle width direction. [0003] For example, the following proposals have been made for such a front subframe: as shown in the following patent document 1, the structure in which the tie rod support part 2 supports the crush box 1e; 2, there is also a front subframe structure such as a steering rack 7 arranged below the tie rod support portion 1a. [0004] In such a front subframe, in order to lower the load bearing point such as the frontal collision load, it is necessary to arrange the sub crush box as low as possible. [0005] On the other hand, although the steering rack...
