Abstract
A torque fluctuation absorbing apparatus includes a torque input member coaxially assembled with an output member through a plurality of circumferentially equally spaced resilient elements in such a manner that the resilient elements are enclosed by the torque input member and maintained in engagement with the torque input and output members to transmit input torque from the input member to the output member. The output member has a hub portion formed with a plurality of circumferentially equally spaced through holes through which a plurality of mounting bolts are inserted and threaded into a hub portion of the torque input member for connection to a drive shaft. The through holes of the output member are each formed to contain the head portion of one of the mounting bolts in such a manner as to permit relative rotaion of the torque input and output members. The through holes of the output member are each formed with an internal surface for engagement with the head portion of the respective mounting bolts in the event the resilient elements are damaged.
