Zusammenfassung:PROBLEM TO BE SOLVED: To reduce resonance of a dual mass flywheel in an engine starting rotational area of an idle speed or less. SOLUTION: This dual mass flywheel 1 has a primary flywheel 11 connected to a crankshaft 100 and a secondary flywheel 12 on the clutch side, and is formed by connecting these primary flywheel 11 and secondary flywheel 12 via a torsion spring (an elastic body) 13. A dynamic damper 2 is arranged in the secondary flywheel 12. Mass of a mass member 21 of its dynamic damper 2 and a spring constant of the elastic body 22 are adjusted, and the resonance of the dual mass flywheel 1 in the engine starting rotational area is reduced by tuning a resonance frequency of the dynamic damper 2 to a resonance frequency of the dual mass flywheel.
