PROBLEM TO BE SOLVED: To increase vibration damping performance against fine torsional vibration in idling in a damper mechanism used in the torque transmission route of a vehicle. SOLUTION: This damper mechanism is installed in the torque transmission route of the vehicle, and transmits torque and attenuates and absorbs the torsional vibration. The damper mechanism comprises a first damper 59 for realizing the characteristics of low rigidity in the first area of torsional characteristics with small torsional angle and a second damper 60 for realizing the characteristics of high rigidity in the second area of the torsional characteristics with large torsional angle. The first damper 59 realizes, in the torsional characteristics, a first low rigidity area A and a second low rigidity area B lower in rigidity than the first low rigidity area A and lower in rigidity than the second area.
