The number of the rollers 32 in each rolling groove 312 is at least 2 which are equally distributed in the thickness direction of the rotary gear 31, which is advantageous in that the rotary gear 31 and the rollers 32 are uniformly stressed when the output lever 4 rotates.
As a preferred embodiment of the present application, specifically, the reduction mechanism 2 is a planetary reduction gear set, which includes a housing 21, and the housing 21 is assembled with a sun gear 22, a planetary gear 23, a carrier 24 connecting the planetary gears 23, and a ring gear 211 provided on an inner wall of the housing 21.
