Claims

[Claims for Utility Model Registration] A cylindrical boss attached to a rotating shaft,
For a pulley body having a cylindrical part located on the radially outer side of the boss part and a connecting part connecting the boss part and the cylindrical part, the pulley body has a substantially cylindrical shape so as to be located in the inner space of the cylindrical part. By arranging the damper masses concentrically and connecting one end surface of the damper mass in the axial direction to the connecting portion via a rubber elastic body, the main portion of the damper mass can be A damper pulley in which the damper mass is elastically supported in a cantilever structure with respect to the pulley main body so as to be located substantially inside in the radial direction of the damper pulley than the connection portion made of a rubber elastic body. and an annular attachment part that is attached to the connecting part of the pulley body via the rubber elastic body on one axial end surface, and an annular attachment part that is integrally assembled to the attachment part and that is substantially larger than the attachment part. and an annular mass body located radially inwardly to form the damper mass, and a ring-shaped mass body located on the inner side in the radial direction constitutes the damper mass, and a part protruding toward the other between the opposing surfaces of the mass body and the boss. A damper pulley characterized by being equipped with a stopper rubber.
