A vehicle floor structure is disclosed to prevent a frame from damaging a fuel tank at collision without lowering the strength of a cross section of a tubular frame. The vehicle floor structure provided by the invention has a vehicle part (20) that stores liquid on the floor. At the cross sections of a plurality of tubular frames (14, 17, 19) that form the vehicle floor, one end of the long side of a second frame (19) is against and is fixed on the lateral side of the first frame (14); and a lower plate part (197) protruding along the long side direction from one end of the second frame (19) is fixed on the lower surface of the first frame (14) by covering the lower surface of the first frame (14); the lower plate part (197) of the second frame (19) that covers the lower surface of the first frame (14) is covered by a protection plate (177) from the vehicle part (20) direction; and the protection plate (177) is fixed on the lower surface of the first frame (14). |
