Abstract: A centrifugal pendulum-type vibration absorbing device that includes a support that rotates together with any one of the rotary elements of the damper; and a mass that is supported by the support so as to oscillate freely, wherein the centrifugal pendulum-type vibration absorbing device is designed to have an effective order that is greater by at least a correction amount associated with the hysteresis of the damper than an order of vibration that is generated in the driving device to be damped.

Abstract: In a starting device including a centrifugal-pendulum vibration absorbing device, while lock-up is released, a flow of working oil directed from a lock-up piston side toward a damper mechanism is produced in a clutch engagement chamber. A thrust force in the axial direction directed from the lock-up piston toward the damper mechanism is applied to a weight, of a mass body of the centrifugal-pendulum vibration absorbing device, disposed on the lock-up piston side. A support member of the centrifugal-pendulum vibration absorbing device is provided with weight support protrusions that project in the axial direction of an input shaft of a speed change device toward the weight disposed on the lock-up piston side.
