For example, a portion on the flange 126 side is cut from a portion in which the flange 126 extending toward the vehicle upper side is formed on the vehicle width direction outer side portion 22A (see the imaginary line in FIG. 10). What is necessary is just to use. As a result, a common floor panel 22 can be used for the low floor sliding door vehicle and other vehicles, and the processing of the floor panel 22 used for the low floor sliding door vehicle can be minimized. An increase in cost can be suppressed.

  Further, the outlet 92B of the drainage channel 92 faces the outside in the vehicle width direction. Therefore, it is possible to suppress the water splashed from the lower side of the vehicle from flowing backward toward the floor panel 22 through the drainage channel 92.

  In addition, since the lower flange 52 and the lower flange 70 are connected by a plurality of spot welded portions 76 arranged at intervals in the longitudinal direction of the vehicle, the water W stopped at the water stopping portion 88 is It drains to the vehicle lower side also through the clearance gap between the welding parts 76 (refer FIG. 1, FIG. 2).

  Next, a modification of one embodiment of the present invention will be described.

  As shown in FIG. 5, the floor panel 22 may be provided with a drainage structure 94 to the vehicle lower side inside the water stop portion 88 in the vehicle width direction. That is, in the drainage structure 94, a through hole 96 is formed in the floor panel 22, and a drainage patch 98 is provided in the through hole 96. As shown in FIG. 6, the drainage patch 98 includes a coupling portion 100 that is formed to be spaced apart in the vehicle front-rear direction, and a water guide portion 102 that is formed between the coupling portions 100.

  As shown in FIG. 5, the connecting portion 100 is connected to the floor panel 22 by, for example, welded portions 104 and 106 formed by spot welding in the vehicle width direction. As shown in FIG. 7, the water guide 102 is configured to discharge water W passing through the through hole 96 to the vehicle lower side while guiding the water W inward in the vehicle width direction. The water guide portion 102 may be configured to guide and discharge the water passing through the through-hole 96 to the outside in the vehicle width direction (may be configured to be reversed to the left and right in FIG. 7).
