Structure for front of vehicle body

摘要

A structure for the front of a vehicle body includes front side frames. The front side frames have bend portions in the rear portion thereof, the bend portions sloping downwards along a dashboard lower panel as the front side frames extend towards the back of the vehicle body. Side sill-side extensions curve to the side of side sills from the end parts of the bend portions. Curving tunnel-side extensions curve towards a tunnel portion. The side sill-side extensions and the tunnel-side extensions form branched portions branching at substantially the same angle. Triangular load support portions are formed at the back of the branched portions between the side sill-side extensions and the tunnel-side extensions. Rear end support portions for supporting the rear ends of sub frames are provided to the bend portions and the fronts of the load support portions.
