<P>PROBLEM TO BE SOLVED: To provide a bending mechanism which achieves bending operation in the range of ±90° per one degree of freedom only by directly sliding a pair of multi-joint links, and carries out multi-degree-of-freedom bending by combining the bending mechanisms with each other. <P>SOLUTION: According to the bending mechanism, first, second, third frames 1, 3, 5 are sequentially pivoted on each other by first and second rotation shafts 2, 4, and arranged in series. On the right of the first rotation shaft 2 of the first frame 1, first, second, and third driving links 7, 9, 12 are connected to each other. On the left of the first rotation shaft 2 of the first frame 1, first and second binding links 15, 17 are connected to each other. According to the bending mechanism thus formed, when the third driving link 12 is driven for sliding, the first frame 1 is rotated rightward and leftward. <P>COPYRIGHT: (C)2004,JPO |
