Zusammenfassung:PROBLEM TO BE SOLVED: To provide a reduction gear of a double planetary differential gear capable of transmitting force from an input shaft efficiently and smoothly. SOLUTION: This reduction gear 1 of the double planetary differential gear includes a first planetary gear 51 provided with a first sun gear 21 and a second sun gear 22 on the input shaft 2 and revolving while meshing with a fixed internal gear 3 and the first sun gear 21 and a second planetary gear 52 revolving while meshing with a driven internal gear 4 and the second sun gear 22. The specifications of the gear such as module and profile shift of at least either of the first planetary gear 51 and the second planetary gear 52 are adjusted to maintain a predetermined reduction gear ratio, and the first planetary gear 51 and the second planetary gear 52 are arranged on a common planetary gear shaft 6.
