PROBLEM TO BE SOLVED: To smoothly open/close a door body as an extremely simple structure which does not clip foreign matters, fingers or others like a gear. SOLUTION: A first main body 1A and a second main body 1B are coupled to each other to be rotated in a folding surface by two connection tools comprising a first connection tool 2 and a second connection tool 3 in a hinge. The first connection tool 2 has one end connected to the first main body 1A through a connection shaft 4 and the other end connected to the second main body 1B through the connection shaft 4. The second connection tool 3 has one end connected to the first main body 1A through a connection shaft 5 and the other end connected to the second main body 1B through the connection shaft 5. The first connection tool 2 and the second connection tool 3 do not interfere with each other and are arranged to be displaced in directions of the connection shafts 4, 5. The first connection tool 2 and the second connection tool 3 are coupled to different positions in a folding face of the first main body 1A and the second main body 1B. The first main body 1A and the second main body 1B are coupled to each other to be shifted 180°at least from mutually parallel posture to linearly arranged posture. COPYRIGHT: (C)2006,JPO&NCIPI
