Then, both ends of the sheet 10 and the core material 11 are sandwiched between the C-shaped portions 21 of the holding member 20, and the sheet lower portion 13 where the core material 11 of the sheet 10 is not provided is disposed between the lower end of the holding member 20 and the floor surface 6. It is drawn out on the floor surface 6 and extended toward the outdoor side along the surface 5 a of the skirting board 5 and the floor surface 6.

  Then, the width | variety of the sheet | seat 10 is larger than the width W (refer FIG. 2) of the opening part O, and is set to the width | variety shown below. That is, the sheet 10 has slack in a state where both ends of the sheet 10 are held by the holding member 20. That is, the holding member 20 holds the sheet 10 in a state in which the sheet 10 has a slack, and allows the sheet 10 to bend toward the opening / closing door 4 side with respect to the holding member 20 and to contact the predetermined portion 51. Therefore, in a state where the seat 10 is held by the holding member 20, the seat 10 is placed along the wall surfaces 3 a and 3 b and the doors 4 a and 4 b of the open / close door 4, and the doors 4 a and 4 b of the wall surfaces 3 a and 3 b and the open and close door 4 are placed. Can be installed in contact with each other. In addition, it is preferable that the sheet 10 has a slack enough to be in close contact with the doors 4a and 4b and the wall surfaces 3a and 3b of the open / close door 4 before being held by the holding member 20 and being subjected to water pressure. .

  In addition, the vertical length of the seat 10 is longer than the vertical length of the predetermined portion 51 of the door 4 and is set to the following length. That is, in a state where the sheet 10 is held by the holding member 20, the sheet lower portion 13 can be hung on the floor surface 6 and can be along the surface 5 a and the floor surface 6 of the skirting board 5. The seat 10 is installed in a state in which the seat lower portion 13 is extended toward the outdoor side along the surface 5 a and the floor surface 6 of the skirting board 5. In other words, the seat 10 is disposed such that the seat lower portion 13 faces the surface 5a and the floor surface 6 of the skirting board 5 and is separated from the open / close door 4 toward the front end side.

  And as shown in FIG. 3, the adhesive surface 31 of the one end part 30a of the adhesive tape 30 in which the adhesive surfaces 31 of the center part 30c were affixed is affixed on the upper end part 12 of the sheet | seat 10, and the other end of the adhesive tape 30 The adhesive surface 31 of the part 30 b is attached to the doors 4 a and 4 b of the opening / closing door 4. Thus, the seat 10 integrally covers the predetermined portion 51 and the portion of the wall surface 3a, 3b adjacent to the predetermined portion 51, and the lower portion 13 of the seat extends outward along the surface 5a and the floor surface 6 of the skirting board 5. In the existing state, the upper end portion 12 of the sheet 10 is fixed to the doors 4a and 4b of the open / close door 4 by the adhesive tape 30, whereby the sheet 10 is fixed to the surface 5a and the floor surface 6 of the skirting board 5 and the wall surface 3a of the structure S. , 3b and the doors 4a and 4b of the door 4 are pressed. The adhesive tape 30 suppresses the sheet 10 from sagging and can be held above the position of the water level aimed at the upper end portion 12 of the sheet 10. Thus, the waterproof device 1 is assembled.
