  • Patent number: 9416845
    Abstract: A damper with a torque limiter is provided in which a torque limiter is formed from an annular limiter housing formed on a mass ring, a friction plate frictionally engaging with the limiter housing a pressure-applying plate that frictionally engages with the friction plate and that is linked to the mass ring, and a limiter spring urging the pressure-applying plate toward the friction plate side, a spring holder is formed from a pair of first and second holder plates that oppose each other to define a damper housing and that are joined to each other by a rivet, and the friction plate is formed integrally with the second holder plate. Thus, a rivet providing a link between a pair of holder plates forming a spring holder does not carry the burden of torque transmission, enabling the diameter of the rivet to be smaller and thereby reducing weight and cost.
