PROBLEM TO BE SOLVED: To facilitate the in-and-out of a person from an opening even when pressure in a body of an air dome drops. SOLUTION: A support frame 160 is mounted around the in-and-out opening 120 provided at the side face of the body 110 formed of a membrane material and kept in a dome shape by air supply. The support frame 160 is self-supportable and has hardness to the extent of maintaining the shape of the opening 120 even when the body 110 collapses due to the drop of internal pressure. The support frame 160 has predetermined hardness by charging air into the hollow. COPYRIGHT: (C)2006,JPO&NCIPI
