Claim Text:
1. A centrifugal pendulum damping device comprising: a rotating shaft whose rotational speed varies; a support body that is provided on the rotating shaft; a plurality of inertial masses respectively supported on a plurality of regions divided in a peripheral direction of an outer peripheral part of the support body; a pair of first curved tracks provided in each of the plurality of regions of the support body; a pair of second curved tracks provided in each of the plurality of inertial masses and curved in a direction opposite to that of the pair of first curved tracks; and a plurality of pins rollably fitted in a section where the pair of first curved tracks and the pair of second curved tracks intersect each other, a damping operation being exhibited by the plurality of inertial masses undergoing pendular oscillation in a trajectory according to the shape of the pair of first curved tracks and the pair of second curved tracks with respect to the support body, wherein the pair of first curved tracks have different shapes from each other, and the pair of second curved tracks have different shapes from each other.
