Abstract

Eccentric oscillation reduction gear (10) comprising: an internal gear (16); an outer gear (14) that meshes with the inner gear (16); a wave of an eccentric body that sets the outer gear (14) into oscillations; and a carrier which is arranged in an axial direction on a side section of the external gear (14), wherein the support comprises a first support (18) arranged on one side in the axial direction of the external gear (14) and a second support (20) arranged on the other side in the axial direction of the external gear (14), where a driven element (50) is connected to the first support (18), the first support (18) is made of a metal and the second support (20) is made of a resin.
