Abstract
A centrifugal pendulum damping device includes a support body provided with a pair of first curved tracks and fixed to a rotating shaft, inertial masses provided with a pair of second curved tracks and supported on an outer peripheral part of the support body, and pins rollably fitted in a section where a first and second curved track intersect each other. Since the shapes of the pair of first curved tracks are different from each other and the shapes of the pair of second curved tracks are different from each other, the inertial mass moves rotationally and translationally in the peripheral direction of the support body, which improves damping low frequency vibration performance. Since the inertial mass moves rotationally, it is less likely to extend outside the region of the support body.
