Abstract
A torque fluctuation inhibiting device includes first and second rotatable rotors, a centrifugal element and a cam mechanism. The first rotor includes an accommodation portion. The second rotor is rotatable with and relative to the first rotor. The centrifugal element is disposed in the accommodation portion to be radially movable, and receives a centrifugal force generated by rotation of the first or second rotor. The cam mechanism receives the centrifugal force acting on the centrifugal element, and converts the centrifugal force into a circumferential force directed to reduce rotational phase difference between the first and second rotors. The cam mechanism includes a cam surface provided on the centrifugal element, and a cam follower which contacts the cam surface. The cam follower transmits a force therethrough between the centrifugal element and the second rotor. The centrifugal element is radially moved while rolling on an inner wall surface of the accommodation portion.
