When opening and closing the landing door 1, the lower gap between the landing door 1 and the threshold 4 fluctuates depending on the state of the landing door 1 and the threshold 4. If the portion 6g from the pressure-contacting portion 6e to the bottom surface 4b of the airtight member 6 to the attachment portion 6f to the door main body 1b is strong, the bottom gap is opened and closed. When this becomes small, the lower hermetic material 6 is pressed, and the resistance between the lower hermetic material 6 and the threshold 4 becomes large too much, and there exists a possibility of the door opening / closure failure / joint generation. For this reason, by forming the curved surface part 6h in the part of the shape of this airtight material, the force which the lower airtight material presses is made small, and even if a lower space | interval is small, resistance will not become large.
