And screwed into the corresponding synthetic wood 4. Thereby, the edge parts of the adjacent floor pan 1 can be connected using the connecting plate 19 and the screw 20. Further, in this case, since the screw 20 is screwed into the synthetic wood 4 which is superior in water and water resistance compared to natural wood or the like, this portion can be more reliably stopped. For this reason, it can suppress appropriately that water leaks out from the part in which screw 20 was passed in floor pan 1.

  In the present embodiment, the cover member 22 is attached to the upper surface of the connecting plate 19 via a waterproof tape 23 whose both surfaces are adhesive surfaces. For this reason, water leakage from between the connecting plate 19 and the cover member 22 can be made difficult to occur by the waterproof tape 23. Moreover, since the head of each screw 20 is covered with the waterproof tape 23, it is possible to further suppress the leakage of water from the portion of the floor pan 1 through which the screw 20 is passed.

  Further, the floor pan 1 of the present embodiment is formed with an edge piece portion 9 that protrudes downward from an end edge on the other floor pan 1 side of the bottom portion of the recess 6, and the reinforcing tool 3 is a lower surface of the bottom portion of the recess 6. And provided along the side surface of the edge piece 9. For this reason, it can prevent that the edge piece part 9 warps so that it may spread outside after shaping | molding of the floor pan 1.
