In a vehicle, a floor member reinforcing member extends in a vehicle longitudinal direction within a closed cross-section portion that is formed by a floor member and a floor panel. The floor member reinforcing member intersects a second floor cross member as seen in plan view. Namely, a portion, that is reinforced by the floor member reinforcing member, of the floor member extends in the vehicle longitudinal direction so as to include a portion, that intersects the second floor cross member, of the floor member. Further, occurrence of bending due to collision load at the portion, that is reinforced by the floor member reinforcing member, of the floor member is suppressed. The reinforced portion of the floor member is displaced toward a vehicle obliquely upper front side following displacement of the second floor cross member toward a vehicle obliquely upper front side.
