Structure for lower vehicle body of vehicle front part

Abstract

Improvement of the rigidity of the lower vehicle body is achieved without a weight increase and the like, a load applied from the vehicle front is dispersed by efficiently smoothly transmitting the load to portions in the vehicle rear such as dash side members, floor side members, and side sills, to reduce deformation of the lower vehicle body. [Solving Means] A suspension frame 10 is fastened to connection parts of front side members 4 and floor side members 5. Dash side members 11 are provided in such a manner as to extend from the fastening parts P ofthe suspension frame 10 obliquely rearward and outward in a vehicle width direction. Outer end parts of the dash side members 11 are connected to front end parts of side sills 7. Front surfaces 6a oflower parts of side outer panels 6 are arranged ahead of the front end parts of the side sills 7. Flanges 6b, 2a, and 3a extending in a vehicle up-down direction are provided to front end parts of the side outer panels 6, dash side inner panels 2, and dash side outer panels 3. The dash side outer panels 3, the side outer panels 6, and the dash side inner panels 2 are connected together by means of the flanges 3a, 6b, and 2a at positions of the front surfaces 6a of the lower parts of the side outer panels 6. The front surfaces 6a of the lower parts of the side outer panels 6 are each formed into an inclined surface which is inclined obliquely downward toward the vehicle rear in the side view and is obliquely rearward toward the outside of the vehicle in the top view. *
