A clutch disk assembly 1 has a pair of axially facing plates 12 and 13. A relatively rotatable flange 8 is provided between the plates 12 and 13. A first elastic member 30 exhibits high rigidity on the positive side of the torsional characteristics. A second elastic member 31 is provided to operate in parallel with first elastic member 30 to realize a low rigidity on the negative side of the torsional characteristics. The stop pins 22 affix plates 12 and 13 together. The stop pins 22 and notches 8c are provided on the outer periphery of the flange 8 constitute a stopper mechanism 86 for regulating the relative rotation between the plates 12 and 13 and the flange 8. The stopper mechanism 86 is located on radially outside the second elastic members 31. The stop pins 22 are movable on the outer periphery of the second elastic members 31.
