Abstract
A torque fluctuation absorber includes a seating member having a pivoting portion at an inner portion in a radial direction and a supporting portion, which rotationally supports the pivoting portion, at an end surface in a circumferential direction of a first and a second opening portion. When no relative rotational torsion existing between a first and a second rotational member, the pivoting portion is in contact with the supporting portion and a clearance is defined between a portion on each seating member positioned outwardly in a radial direction relative to the pivoting portion and a portion of the first and the second opening portion positioned outwardly in a radial direction relative to the supporting portion. At a first torsion angle, the portion on each seating member contacts the portion of first or second opening portion in a state where the pivoting portion is in contact with the supporting portion.
