Patent ID: 7819751

Claim:
A torque fluctuation absorbing apparatus, comprising: a first component member; a second component member being movable relative to the first component member; a third component member movable relative to the first component member and the second component member in a circumferential direction; an elastic member biasing the third component member in a direction to contact either one of the first component member and the second component member so as to contact the third component member with either one of the first component member and the second component member; and a pressing generating mechanism provided at the third component member and the other of the first component member and the second component member for generating pressing force in an identical direction to the direction of the biasing force by the elastic member in response to relative speed and/or relative acceleration when the first component member moves relative to the second component member in the circumferential direction, wherein, when the relative speed and/or relative acceleration between the first component member and the second component member is smaller than a predetermined speed and/or acceleration, the pressing force is smaller than a predetermined force due to restriction of the relative rotation between the third component member and the other one of the first component member and the second component member.
