Deformation of a vehicle compartment is suppressed at the time of a small overlap collision. A front pillar lower structure () includes a gusset () joined to a lower end portion of a pillar reinforcement (). In the gusset (), a front wall (B) and a lower wall (C) extend from a side wall (A) located on the outer side in a vehicle width direction of a rocker reinforcement. The front wall (B) covers the rocker reinforcement () from the vehicle front side, while the lower wall (C) extends toward the vehicle rear side from a lower end of the front wall (B) and is joined to a lower surface of the rocker reinforcement (). Since the strength of a joint portion () between the pillar reinforcement () and the rocker reinforcement () can be improved by the gusset (), it is possible to prevent or suppress breakage of the joint portion () at the time of a small overlap collision so that deformation of a vehicle compartment () due to such breakage can be suppressed.

Automobile front pillar lower structure

A vehicle-body front structure that is able to secure collision performance for a collision with a small overlap amount of a collision object with respect to a bumper frame portion is obtained. A vehicle-body front structure includes: paired frame members elongated in a vehicle front-rear direction and arranged side by side in a vehicle width direction; a bumper frame portion elongated in the vehicle width direction and provided over front ends of the paired frame members in the vehicle front-rear direction; and a load transmission member. The load transmission member is placed on an inner side in the vehicle width direction relative to at least one of the frame members so as to be opposed to a load receiving portion placed between the paired frame members from at least one of a front side in the vehicle front-rear direction and an outer side in the vehicle width direction within a range where the load transmission member overlaps with the frame member in a vehicle up-down direction.
