  • Patent number: 9828032
    Abstract: A vehicle front section structure includes a front side member, a gusset that juts out from a side face of a front end of the front side member, a bumper reinforcement that is disposed at a front end side of the vehicle body front section, and a crash box that is disposed between front ends of the front side member and the gusset, and an outer side section of the bumper reinforcement, that couples both of the front ends and the outer side section together, and undergoes compressive plastic deformation due to collision load. A flat portion is integrally formed at an end of the bumper reinforcement, with a front face of the flat portion extending along the vehicle width direction and a vehicle up-down direction and, in vehicle front view, overlapping with a side wall portion at the vehicle width direction outer side of the crash box.
