ABSTRACT:
A torque vibration absorbing device includes a clutch hub with a flange extending radially, a pair of intermediate plates disposed at both outsides of the flange so as to be rotatable relative to the flange, a disc plate and a sub-plate disposed at the outside of the intermediate plates so as to be rotatable relative to the flange and the intermediate plates, a plurality of connecting pins which connect the disc plate and the sub-plate, and a plurality of elastic members provided in series at the inside of the disc plate and the sub-plate through the intermediate plates, wherein at least one elastic member is maintained at a predetermined amount of compression when a torsional degree between the flange and each of the disc plate and the sub-plate is changed to be larger than the predetermined amount thereof and the other elastic members are continued to be compressed exceeding the predetermined amount of compression.
