Abstract

It is possible to provide a more compact planetary reduction gear. Provided is a planetary reduction gear 10 configured to have an external gear 14, an internal gear 16 with which the external gear is internally meshed, and a pair of first and second carriers 21 and 22 respectively arranged on both axial sides of the external gear in a casing 12. Furthermore, the casing and the internal gear are configured to be separated from each other and the internal gear is disposed on an inner circumference of the casing. In addition, first and second main bearings 41 and 42 that support the pair of the first and second carriers are respectively disposed on both axial sides of the internal gear, and the first and second main bearings are supported by the casing without intervention of the internal gear. Further, one axial end of the internal gear is axially positioned by a retaining ring 50 that is disposed between the internal gear and the first main bearing 41 and fixed to the casing, and the other axial end of the internal gear is axially positioned by an outer ring 42B of the second main bearing 42.
