[0005]

In the above conventional floor structure, as shown in FIG. 7, in order to secure the sealing property at the rear end of the concave bead 11 facing the notch 12, as shown in FIG.
By bending the front edge portion 91 of the slope panel 9 into an uneven shape following the panel shape of the floor panel 1 in which the concave bead 11 is formed and stacking this on the rear end portion of the concave bead 11, a gap is formed between them. I try not to cause. However, forming the front edge portion 91 of the slope panel 9 into a concavo-convex shape has a problem of high cost because it requires time and effort for production. It is conceivable to eliminate the concave bead 11 of the floor panel 1 at the portion where the front edge portion 91 of the slope panel 9 overlaps, but the floor panel of the base vehicle cannot be diverted, and the cost is inevitably high.

Therefore, the present invention solves such a problem, and an object of the present invention is to provide a vehicle floor structure capable of ensuring the sealing property of a floor with a slope without increasing the manufacturing cost.
