Abstract
A torque fluctuation inhibiting device includes a mass body, a centrifugal element and a cam mechanism. The mass body is disposed in alignment with a rotor in an axial direction, and is rotatable relatively to the rotor. The cam mechanism includes a cam and a cam follower. When relative displacement occurs between the rotor and the mass body due to a centrifugal force that acts on the centrifugal element, the cam mechanism converts the centrifugal force into a circumferential force directed to reduce the relative displacement. Guide parts are provided on both ends of the centrifugal element. Each guide part makes contact with a member adjacent thereto in an opposite position to a contact point between the cam and the cam follower through a center of gravity of the centrifugal element when the relative displacement occurs between the rotor and the mass body in the rotational direction.
