At a vehicle, rockers and torque boxes are connected, from a front side, to first connecting portions of spacers. Joined portions of the rockers and the torque boxes are reinforced, and a front wheel directly hitting the joined portion at a time of a collision is suppressed. Separation of a joined portion of a front pillar and a dash panel, whose origin is separation of the previously-mentioned joined portion, can be suppressed. Front portions of the spacers are disposed further toward a front side than the joined portions of the front pillars and the dash panel. Therefore, the front wheel first hits the spacer, and collision load is transmitted to the rocker and the torque box, and thus, input of an excessive collision load to the dash panel is suppressed. Because the first connecting portions extend in a vehicle transverse direction, the spacers becoming large can be suppressed.

Vehicle body front portion structure

In a vehicle, a gusset is provided at a lower end portion of a front pillar, a body wall portion of the gusset is joined to the front pillar, and a bottom wall portion of the gusset is joined to an upper wall portion of a rocker outer reinforcement. Thus, when the front pillar is about to collapse rearward, the upper wall portion supports the bottom wall portion of the gusset from below the vehicle. Therefore, the front pillar is restrained from collapsing. Besides, the rocker outer reinforcement receives, on a surface thereof, a load input from the gusset. Therefore, the load input to the rocker outer reinforcement is dispersed, so the load can be restrained from concentrating.
