A single cross member extending in a vehicle width direction is provided between a portion of a side sill which is positioned near a center pillar and a tunnel portion. A pair of seat-rail mounting seats are provided at a lower portion of the tunnel portion to be spaced apart from the cross member in a vehicle longitudinal direction. A seat rail is rigidly connected to the pair of seat-rail mounting seats at its bottom face. Thereby, the lightweight, high rigidity, and quietness of the vehicle can be attained.
