Abstract

[Problem] To provide a lower vehicle-body structure that allows a load applied to a side sill from a vehicle-width-direction outer side to be efficiently transmitted to a cross member. [Means for Solution] A lower vehicle-body structure includes a pair of side sills, at least one cross member that couples the pair of side sills together, and a reinforcement extending in a front-rear direction in each of the pair of side sills. The reinforcement includes a first part disposed at a position that overlaps with at least one cross member when a vehicle is viewed in a side view, and a second part disposed at a position that does not overlap with at least one cross member when the vehicle is viewed in a side view. A rigidity of the second part against a load from a vehicle-width-direction outer side is lower than a rigidity of the first part against a load from the vehicle-width-direction outer side.
