A torque fluctuation absorber includes a first damper portion absorbing torque fluctuations caused by a torsion between a first rotary member and a second rotary member, a second damper portion absorbing torque fluctuations caused by a torsion between the second rotary member and a third rotary member, and a stopper portion. The first rotary member includes a first projecting portion projecting radially inwardly and being contactable with the stopper portion by the torsion between the first rotary member and the second rotary member. The third rotary member includes a second projecting portion projecting radially outwardly and being contactable with the stopper portion by the torsion between the third rotary member and the second rotary member. The second projecting portion makes contact with the stopper portion at a radially inner side relative to a portion where the first projecting portion makes contact with the stopper portion.
