PROBLEM TO BE SOLVED: To secure vehicle interior comfort and enhance the rigidity of an intersection portion of a floor bead and a cross member while suppressing increase in the weight of a vehicle body. SOLUTION: The vehicle body is provided with a floor panel 25, the narrow and long floor bead 26 swollen upwardly from the floor panel 25 and extended to the vehicle body longitudinal direction, and the cross member 24 intersecting with the floor bead 26 and extended to the vehicle width direction to overlap with the floor bead 26 from the upper side. In the floor bead 26, the portion 43 intersecting with the cross member 24 is formed to be a narrow bead part narrowed to have the height lower than that of other portions 44 which do not intersect. In the cross member 24, an opening part 35 through which the narrow bead part 43 penetrates is provided on the lower face 34. The floor bead 26 and the cross member 24 are jointed while intersecting with each other by a jointing member 60 having a cross shape in plane view. COPYRIGHT: (C)2009,JPO&INPIT
