ABSTRACT:
A dynamic damper 10 can dampen not only a torsional vibration but also an axial vibration. The dynamic damper 10 can operate in a coupling mechanism 1 to perform an operation interlocked with an input shaft 9 of the transmission. The dynamic damper 10 includes a mass member 11, a sub-clutch 13 and an elastic portion assembly 12. The coupling mechanism 1 has a main clutch 3 which is operatively coupled between a crankshaft 8 of an engine and an input shaft 9. The mass member 11 can selectively rotate with the input shaft 9 upon engagement of the sub-clutch 13. The sub-clutch 13 releases an interlocked relationship between the input shaft 9 and the mass member 11 when the main clutch 3 disengages the crankshaft 8 from the input shaft. The elastic portion assembly 12 includes at least one rubber member, which elastically couples the input shaft 9 and the mass member 11 together in the rotating and axial directions when the sub-clutch 13 interlocks the input shaft 9 and the mass member 11 together.
