PROBLEM TO BE SOLVED: To provide a link mechanism capable of moving parallel in arbitrary directions such as fore-and-aft and right-and-left directions.SOLUTION: A first rod 10 is provided which has one end and the other end connected freely to a lower support body 2 and an upper support body 3, respectively and forms a swinging link A. Similarly, a second rod 2 which has one end and the other end connected freely to the lower support body 2 and the upper support body 3, respectively and forms a swinging link B, and a third rod forming a swinging link C are provided. In this mechanism, the first rod 10 and the second rod 20 belong to a first parallel link 41, the first rod 10 and the second rod 20 belong to a second parallel link 42, and the second rod 20 and a third rod 30 belong to a third parallel link 43. The first rod 10 to the third rod 30 are restricted in rotation around the axial line. A support device 1 can be move a display device 50 parallel without changing an orientation of the display device fixed on the upper support body 3. |
