PROBLEM TO BE SOLVED: To provide a torque fluctuation absorber capable of stabilizing limiter torque by eliminating a friction material, and capable of absorbing toque fluctuation. SOLUTION: The torque fluctuation absorber is provided with a first plate 81 disposed on a crankshaft 39 and having a recession 83 and a protrusion 84 formed continuously along a circumferential direction, a second plate 82 provided on an input shaft 46 so as to confront the first plate 81 and rotatably holding spherical bodies 85 and 90 by a confronting surface 82a confronting the first plate 81, and a compression spring 87 energizing the second plate 82 to the first plate 81 so that the first plate 81 and the second plate 82 approaches with each other. The protrusion 84 is formed in a chevron-shape having a first tilt surface 84a upwardly tilted to one side of the circumferential direction of the first plate 81 and a second tilt surface 84b downward tilted to one side of the circumferential direction of the first plate 81 from the vertex of the first tilt surface 84a.
