Problem to be Solved by the Invention A collar 4t is connected to the closing plate 1, and the front suspension member 6t is connected to the upper and lower walls 3a and 3b of the front side member 3 through the collar 4t.
Even if the bolts and nuts are tightened 7.8, if an excessive suspension input is applied from the 70-ton suspension member 6 to the front side member 6, the angle of the corner of the front side member 3 will change and the cross section will be closed. This tends to cause deformation, which is disadvantageous in terms of strength and soundproofing/vibration proofing. In particular, when the spring mount bracket 9 is joined to the side surface of the closing plate 1 and the suspension input from the coil spring 10 also acts, the closing plate 1 tends to fall inward and deform due to the human force of the suspension. The above-mentioned problem will be further exacerbated. Therefore, the present invention has a simple configuration that suppresses changes in the angle of the corners of the front side member and increases the mounting strength.
The present invention provides a front suspension member mounting structure that can take thorough anti-vibration measures.

According to the structure of the above embodiment, the stiffener 11 formed integrally with the pair of collars 4.4 is joined across between the closing plate 1 and the side wall 6C of the front side member 6. Since the stayer +-11 functions as a tension member between the closing plate 1 and the width of the front side member 6, it can sufficiently resist the suspension input from the front suspension member 6, and It is possible to suppress the angle change of the corner portion or the deformation of the closed cross section. 17'
C. The suspension human force acting on the spring mount bracket 9 from the coil spring 10 is also placed in place 1.
2 to the hood ledge panel 2 (corresponding to a portion of the strut tower), deformation of the closed section can be further suppressed.
