PROBLEM TO BE SOLVED: To solve problems of interference and frontage dimension which arise when a door having equipment installed on an internal side thereof is opened. SOLUTION: When the degree of opening of an internal door 11 is large, the internal door 11 and an intermediate member 13 are rotated in one body about a first rotating shaft 14. On the other hand, when the degree of opening becomes smaller, a second rotating shaft 15 is positioned and the intermediate member 13 is also positioned, whereby only the internal door 11 is rotated about the second rotating shaft 15.
