Torque fluctuation absorber

A torque fluctuation absorber, comprising:

• a first plate member to which power of rotation is transmitted from a first rotational shaft;
• a second plate member arranged at a preset distance from the first plate member;
• a third plate member arranged between the first and second plate members and configured to transmit power of rotation to a second rotational shaft;
• a fourth plate member arranged at a preset distance from the second plate member;
• and
• a resilient member arranged between the second plate member and the fourth plate member and configured to bias the second plate member towards the third plate member;
• the resilient member including a first end located at a position having a preset distance from a center of rotation of the first rotational shaft and a second end located at a position more closely to the center of rotation of the first rotational shaft than the first end;
• the first end abutting against the second plate member in an area where the second plate member faces the third plate member in the axial direction;
• the second end abutting against the fourth plate member.
