ABSTRACT:
A damper assembly for a clutch has an annular cover assembly including a pair of first covers adapted to be connected to a torque input part and a pair of second covers; an annular first hub connected to the second cover; an annular second hub adapted to be connected to a torque output part; a wake first torsion spring mechanism connecting the first covers to the first hub; a strong second spring mechanism connecting the second covers to the second hub; and a stopper mechanism for preventing relative torsion between the first covers and the first hub when a torsion angle between the first covers and the first hub increases to predetermined values at positive and negative rotating directions; the stopper mechanism is so designed that the predetermined values of the torsion angle in the positive rotating direction and the negative rotating direction may be different from each other; and the second torsion spring mechanism includes a plurality of springs arranged in series with floting spacers therebetween.
