Claims

[Scope of utility model registration request]

A planetary gear 4 is meshed with a sun gear 3 fixed to an input shaft 2 supported on a fixed side, and this planetary gear 4 is meshed with a ring gear 5 rotatably supported on a fixed side to form a planetary gear mechanism. The outer race 7 is rotatably supported on the outer circumferential surface of the output shaft 9, and the teeth 8 formed on the outer circumferential surface of the outer race 7 mesh with the teeth 10 formed on the inner circumferential surface of the output shaft 9 to form a small number tooth differential reduction mechanism. A speed reduction device characterized in that the outer peripheral side of the ring gear 5 is rotatably supported on a fixed side via a bearing 11.
