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.
