<p>PROBLEM TO BE SOLVED: To provide a turning mechanism that has a high degree of freedom in designing, can be miniaturized and made light, and allows disassembly maintenance to be made easily. SOLUTION: The turning mechanism 1 comprises an annular outer wheel 2 having a V-shaped groove 2a on the inner-periphery surface, a first annular, inner wheel member 3 where chamfering 3b is formed at the outer-periphery end of one end face in an axial direction, a second annular, second inner wheel member 4 where chamfering 4b is formed at the outer-periphery end of one end face in an axial direction, and pluralities of bearing balls 5. The first inner wheel member 3 is arranged in the outer wheel 2, pluralities of bearing balls 5 are arranged, and then the first inner wheel member 3 and the second inner wheel member 4 are fixed by a bolt 7, thus easily assembling the turning mechanism 1.</p> |
