It is preferable to install. A hollow 49 is formed in the center portion of the intermediate disk 48 so that the first planetary gear 54 and the second planetary gear 53 are positioned through the hollow 49, so that the first planetary gear 54 is disposed. And the second planetary gear 53 are in contact with the first ring gear 41 and the second ring gear 57 without being in contact with the intermediate disk 48. In order for the intermediate disk 48 to interlock with the rotating disk 62, the fixed shaft 55 protrudes from the front rotating disk 60a, and the through-hole 50 corresponding to the intermediate disk 48 is formed. . Since the fixed shaft 55 is connected through the through hole 50 of the intermediate disk 48, the intermediate disk 48 rotates in association with the rotating disk 62.

The shaft member 44 is installed at the end of the fixed shaft 55 opposite to the front pivot disk 60a. Like the intermediate disk 48, the shaft member 44 is provided with a through hole 46 corresponding to the fixed shaft 55. The fixed shaft 55 penetrates the through hole 46 so that the shaft member 44 and the front pivot disk 60a are connected to each other. A protrusion 45 is formed at the center of the shaft member 44. The protruding portion 45 passes through the through hole 42 formed in the central portion of the first ring gear 41 to serve as a rotation shaft of the first ring gear 41.
