<P>PROBLEM TO BE SOLVED: To provide a reduction device configured in such a manner that roller guiding bearings which are pressure-fitted on eccentric circular plates of an input shaft are stably installed to suppress reduction in the efficiency due to the coming out of the bearings. <P>SOLUTION: The input shaft 7 is disposed so as to be coaxial with a stationary arranged internal gear 3, two eccentric circular plates 9 which can rotate within the internal gear 3 are provided to the input shaft 7, and roller guiding bearings 11 are pressure-fitted on the respective outer diameter surfaces of the eccentric circular plates 9. A circular protrusion 21 is provided between the two eccentric circular plates 9, and staking protrusions 22 are provided at an axially opposing end of the two eccentric circular plates 9 and an end on the opposite side thereof. The staking protrusions 22 and the annular protrusion 21 prevent the bearing 11 from moving in the axial direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
