The above description is for the case where the waterproof material 30 is used in combination with the blocking material 60, but as described above, the waterproof material 30 and the sealing material 60 are formed separately from each other. Since the waterproof material 30 is not attached to the blocking material 60, the waterproof material 30 can be directly arranged and used on the indoor surface 1B of the hinged door 1 without the shielding material 60, and as described above. In addition, the waterproof material 30 can be indirectly arranged and used on the indoor side surface 1B of the hinged door 1 via the sealing material 60.

In addition, when the waterproof material 30 is directly arranged and used on the indoor side surface 1B of the hinged door 1 without using the blocking material 60, the waterproofing material 30 is used as the hinged door 1 and the door frame 2 when the doorway 8 is closed. The waterproof material 30 may be sandwiched between the two parts, or the waterproof material 30 may be temporarily fixed to the hinged door 1 or the door frame 2 by using a temporary fixing member such as a double-sided adhesive tape.

In this way, when the hinged door 1 is directly arranged and used on the indoor side surface 1B without the shielding material 60, or indirectly arranged on the indoor side surface 1B of the hinged door 1 via the shielding material 60. As described in the embodiment of FIG. 9, the waterproof material in the case of use may be the waterproof material 30 of the embodiments of FIGS. 1 to 6, the waterproof material 40 described with reference to FIG. 7, or the waterproof material 40 of FIG. The waterproof material 50 described in the above may be used. And, like the waterproof material 30, these waterproof materials 40 and 50 are also waterproof materials formed separately from the sealing material 60. When the waterproof material 40 is used, the waterproof material 40 can be selectively attached to the indoor side surface 1B of the hinged door 1 and the sealing material 60 by the magnet 44 provided on the waterproof material 40.

The waterproof material 30 can also be used by being inseparably attached to the sealing material 60 with an adhesive or the like.
