<P>PROBLEM TO BE SOLVED: To reduce product cost by reducing the number of part items and installation manhours. <P>SOLUTION: A plurality of first projections 41 projecting to the second opposed part side of a joint 8 are formed in a first opposed part of an output gear 7. A plurality of second projections 42 projecting to the first opposed part side of the output gear 7 are formed in a second opposed part of the joint 8. The plurality of first and second projections 41 and 42 are alternately arranged in the peripheral direction of a transmission mechanism, and are respectively formed at a 120° interval in the peripheral direction of the transmission mechanism. A plurality of compressive deforming parts 71 and 72 compressively deformable in the peripheral direction of the transmission mechanism are integrally formed in a cushion 9 held between the first opposed part of the output gear 7 and the second opposed part of the joint 8. The plurality of compressive deforming parts 71 and 72 are respectively inserted and arranged between the adjacent first and second projections 41 and 42. First and second connecting parts for connecting the adjacent compressive deforming parts 71 and 72 are integrally formed in the cushion 9. <P>COPYRIGHT: (C)2012,JPO&INPIT |
