PURPOSE:To sufficiently reduce both idling noise and travelling noise by determining hysteresis torque for reducing the idling noise to add viscous attenuation to this hysteresis torque for reducing abnormal sound in traveling. CONSTITUTION:A spring mechanism 12, a torque limiting mechanism 9 and a hysteresis mechanism 7 are interposed between an engine side fly wheel 1 and a transmission side fly wheel 3. And to add viscous attenuation for reducing abnormal sound in traveling, the spring mechanism 12 is equipped with an attenuating body 5 provided integrally with a viscous attenuation generating mechanism 13. |
