<P>PROBLEM TO BE SOLVED: To provide a link actuating device, which has a compact configuration with a small dimension of an outer diameter, which is easily assembled and which can be manufactured at a low cost. <P>SOLUTION: A link actuating device 1 includes link hubs 2, 3 arranged at input and output sides, respectively, and two link mechanisms 4A, 4B. Each link mechanism 4A, 4B is a three-joint chain link mechanism comprising four revolute pairs, in which end links 5, 6 are rotatably joined to the link hubs 2, 3, respectively, and the end links 5, 6 on the input side and on the output side, respectively, are rotatably joined to a center link 7. The link mechanism 4A, 4B has such a positional relationship that the revolute pair axes O1A, O1B (O2A, O2B) of the link hub 2, 3 and the end link 5, 6 are on the same plane and intersect each other. At least one of the two link mechanisms 4A, 4B is provided with an interlocking means 9 for rotating and displacing the end links by interlocking the end link 5 on the input side with the end link 6 on the output side. <P>COPYRIGHT: (C)2013,JPO&INPIT |
