PROBLEM TO BE SOLVED: To vary a damping factor or hysteresis and in its turn, a damping property in relation to angular speed or angular acceleration by varying the damping work of a damper mechanism in relation to the angular speed generated between both inertia bodies based on torque fluctuation or torsional vibration. SOLUTION: A viscous medium being contained in an individual chamber, when relatively moving, is pushed out from the chamber to another chamber, for example. When this viscous medium is pushed out, damping work is generated between both inertia bodies 3 and 4. A hydraulic type damping mechanism 13, a torsion elastic damping device 14 and a friction device 56 are contained in a ring-like chamber 60. In the ring-like chamber 60, the viscous medium or lubricant is contained. The level of the lubricant reaches at least the external turn strip of the pressure accumulation member of the torsion elastic damping device 14 during the turning of a device 1. |
