A torque fluctuation absorber (1) includes a first damper portion (2) absorbing torque fluctuations caused by a torsion between a first rotary member (17) and a second rotary member (20, 21), a second damper portion (4) absorbing torque fluctuations caused by a torsion between the second rotary member and a third rotary member (30), and a stopper portion (7, 22, 40, 20c, 21c). The first rotary member (17) includes a first projecting portion (17a) projecting radially inwardly and being contactable with the stopper portion by the torsion between the first rotary member and the second rotary member (20, 21). The third rotary member (30) includes a second projecting portion (30d) projecting radially outwardly and being contactable with the stopper portion (7, 22, 40, 20c, 21c) by the torsion between the third rotary member (30) and the second rotary member (20, 21). The second projecting portion (30d) makes contact with the stopper portion at a radially inner side relative to a portion where the first projecting portion (17a) makes contact with the stopper portion (7, 22, 40, 20c, 21c). |
