To provide a damper gear capable of preventing a mass body from falling down when an axial length of the mass body is increased.SOLUTION: A damper gear comprises: an installation member (30) mounted on the outer periphery of a power transmission shaft (1); a mass body (10) disposed in an outer diameter direction of the installation member (30) in a radial direction of the power transmission shaft (1); and a connection member (20) composed of an elastic body and connecting the installation member (30) to the mass body (10). The connection member (20) includes: a plurality of first connection members (21) disposed on the one side of the axial direction of the power transmission shaft (1) on an inner periphery of the mass body (10); and a plurality of second connection members (22) disposed on another side of the axial direction of the power transmission shaft (1) on the inner periphery of the mass body (10), in which the first connection member (21) and the second connection member (22) are alternately disposed in the circumferential direction of the mass body (10).SELECTED DRAWING: Figure 2
