PROBLEM TO BE SOLVED: To allow high precision transferring by eliminating backlash while preventing damage due to eccentric wear and excessive stress concentration. SOLUTION: In a gear 10, a tooth 50 is formed in a rib 36 of a first wheel. A tooth 52 is formed in the rib 38 of a second wheel. A tooth 14 is formed by the opposed teeth 50, 52 by engaging the first wheel with the second wheel. An elastic body 44 is provided between the first wheel and the second wheel. When biasing part 48 is elastically transformed, the first wheel and the second wheel are relatively rotated to bring the teeth 50, 52 close to each other. By doing so, backlash can be eliminated while smoothly rotating the gear. COPYRIGHT: (C)2005,JPO&NCIPI
