ABSTRACT:
A torque fluctuation absorber which is unlikely applied with an foreign material such as dust on a limiter portion during transporting the torque fluctuation absorber. The torque fluctuation absorber includes a flywheel for transmitting a driving force from a power source and a damper mechanism having a limiter portion which includes a frictional member being frictionally engaged with the flywheel on an external peripheral side and connected to an input shaft of a transmission on an internal peripheral side. The torque fluctuation absorber further includes a supporting mechanism for performing a frictional engagement of the frictional member by supporting the frictional member in an axial direction of a drive shaft under a condition before assembling the flywheel to the damper mechanism.
