1. A lower vehicle-body structure of a vehicle, comprising:
a side sill having a closed-cross section jointly formed by a side sill outer and a side sill inner which extend in a vehicle longitudinal direction; and
a cross member joined to the side sill inner of the side sill at a position located on a rearward side, in the vehicle longitudinal direction, relative to a front end portion of the side sill and extending toward an inward side, in a vehicle width direction, from the side sill,
wherein said side sill inner comprises an upper face portion and a lower face portion which is downwardly away from said upper face portion, each of which comprises a bending portion, a slant face portion, and a vehicle-width-direction face portion which are respectively located at least in an area, in the vehicle longitudinal direction, between the front end portion of said side sill and said cross member, the bending portion being formed by each of the upper face portion and the lower face portion bent toward an inside of the side sill, the slant face portions being configured to extend from said bending portions toward said side sill outer in an oblique direction such that a width, in a vertical direction, of the side sill inner gradually increases, the vehicle-width-direction face portion being configured to extend in the vehicle width direction toward the inward side, in the vehicle width direction, from said bending portion.
