| description | A torque fluctuation inhibiting device includes a first rotor including an accommodation portion, a second rotor, a centrifugal element, a guide member, and a cam mechanism. The first rotor is rotatable. The second rotor is rotatable with the first rotor and relative to the first rotor. The centrifugal element is radially movable in the accommodation portion at gaps produced circumferentially therebetween, and receives a centrifugal force generated by rotation of the first or second rotor. The guide member guides radial movement of the centrifugal element. The guide member is movable and rollable between both circumferential end surfaces of the centrifugal element and wall surfaces provided in the accommodation portion to be opposed to the both circumferential end surfaces. The cam mechanism receives the centrifugal force acting on the centrifugal element, and converts the centrifugal force into a circumferential force to reduce rotational phase difference between the first and second rotors. |
