Abstract
A centrifugal pendulum vibration absorbing device includes a flange that is coupled to a driven member that is a rotary element that rotates using power from an engine and a mass body that is coupled to the flange so as to oscillate about a pendulum fulcrum PF and is designed so as to have an effective order qthat is greater by a correction amount Δq that is at least associated with the non-linearity of an order q of vibration of the flange and the mass body that is dependent on an oscillation angle ϕ of the mass body than an order qof vibration that is generated in the engine to be damped.
