<P>PROBLEM TO BE SOLVED: To rotate an external tooth gear in a stable state to reduce noise and backlash, and to assemble or dismantle an internal meshing planetary gear device without requiring a special device. <P>SOLUTION: In a reduction gear G1 or a geared motor GM1 provided with an internal tooth gear 130, the external tooth gear 126 internally meshed with the internal tooth gear 130, and an eccentric body 120 for swinging and rotating the external tooth gear 126 to reduce the rotational speed of an input shaft 114 and output it, the eccentric body 120 itself constitutes a part of a clamp structure K1 for friction-connecting the eccentric body 120 with the input shaft 114 directly. <P>COPYRIGHT: (C)2008,JPO&INPIT |
