を簡単に閉塞することができる。As described above, according to the present invention, the apparatus main body constituted by the inflatable and contractible air tube is mounted in a contracted state between the opening of the hatch and the outer periphery of the inserted lid. Then, since the device body is configured so as to close the gap generated between the hatch and the inserted lid by expanding the device main body, the opening of the device main body and the inserted lid are connected to each other. The gap created between the opening of the hatch and the inserted lid can be easily closed simply by mounting it in the gap and inflating it.

ことができる。In the process of inflation, the apparatus body (air tube) expands while deforming in accordance with the shape of the gap formed between the opening of the hatch and the inserted lid, and the outer periphery of the apparatus body Since the surface is in close contact with the edge of the opening of the other hatch and the outer periphery of the lid, a very high sealing property can be exhibited. Furthermore, compared to the case where the above gap is covered with a sheet as in the past, even in a strong wind, the cover is not turned over and the sealing performance is not impaired, and the high sealing performance even in bad weather with strong rainy winds And water or dust can be effectively prevented from entering the hatch.
