Torque fluctuation absorber

A torque fluctuation absorber, comprising:

• a first annular member;
• a second annular member arranged to be axially separated from the first annular member;
• an annular dish-shaped first disc spring arranged between the first annular member and the second annular member;
• a first support portion arranged between the first annular member and the first disc spring and being partially or continuously in contact with the first disc spring on a circle passing through a first predetermined radial portion of the first annular member;
• a second support portion arranged between the second annular member and the first disc spring and being partially or continuously in contact with the first disc spring on a circle passing through a second predetermined radial portion of the second annular member;
• the second predetermined radial portion being radially different from the first predetermined radial portion of the first annular member;
• wherein the first annular member includes a surface facing the first disc spring, the surface of the first annular member being provided with a first recess, the first support portion being positioned in the first recess;
• wherein the second annular member includes a surface facing the first disc spring, the surface of the second annular member being provided with a second recess, the second support portion being positioned in the second recess;
• a third annular member;
• a fourth annular member axially separated from the third annular member;
• an annular dish-shaped second disc spring arranged between the third annular member and the fourth annular member, the second disc spring possessing opposing facing surfaces;
• a portion of the third annular member protruding towards the second disc spring to define a protruding third support portion in partial or continuous contact with one of the surfaces of the second disc spring;
• and
• a portion of the fourth annular member protruding towards the second disc spring to define a protruding fourth support portion in partial or continuous contact with an other of the surfaces of the second disc spring.
