Abstract
A centrifugal pendulum damper in which a rolling mass can be lubricated by a simple structure without limiting vibration damping performance. The pendulum damper comprises: a rotary member; an inertia body arranged concentrically with the rotary member; a rolling mass held in a retainer on an outer circumference of the rotary member; a recess formed on an inner circumference of the inertia body; and a raceway surface formed on an inner circumference of the recess to which the rolling mass is contacted. In the centrifugal pendulum damper, oil remaining in the recess is discharged out of the recess through an oil passage.
