<p>PROBLEM TO BE SOLVED: To realize a smooth movement without complicate structure. SOLUTION: A plurality of middle units 10 of rhombic shape having bearing cylindrical parts at both ridge lines, a first end unit 30 and a second end unit 50 of half-divided rhombic shape having a bearing cylindrical part at one of ridge lines and attaching part at a jointing face are used. A connection shaft 70 is press-fitted to bearing cylindrical parts 12, 12 of the ridge line of the middle units 10 and a bearing cylindrical part 22 of the middle units 10 adjacent to the bearing cylindrical parts 12, 12, and the connecting shaft 70 is press-fitted to the bearing cylindrical parts 12, 12 of the middle unit 10(1) and a bearing cylindrical part 32 of the first end unit 30 adjacent to the bearing cylindrical parts 12, 12, and the connection shaft 70 is press-fitted to a bearing cylindrical part 22 of the middle unit 10(5) and a bearing cylindrical part 52 of the second end unit 50 adjacent to the bearing cylindrical part 22. A plurality of rotation fulcrums by a plurality of connection shafts 70 are included inside this hinge device 100 itself.</p> |
