In lower structures for vehicle front pillars, there are paired right and left side sills arranged in lower portions on both sides of a vehicle, respectively; an outer portion, in a vehicle width direction, of each side sill is formed of an outer reinforcement for a side sill; a inner panel for the side sill is arranged on an inner side, in the vehicle width direction, of each side sill; the front pillars are formed so as to stand on front ends of the side sills, respectively; outer panels for side bodies cover outer reinforcements for the respective front pillars and parts of the respective side sills; each outer reinforcement for side sill is segmented, in the vehicle front and rear direction, into three parts, that is to say, first to third components positioning sequentially from a front of the vehicle; strengths of the first to third components are set to be higher sequentially in this order; and the first, second, and third components are joined and integrated together.
