Abstract
A power transmission apparatus with a centrifugal pendulum damper is realized, which can effectively suppress torque fluctuation and vibration noise of a vehicle while avoiding size increase of a centrifugal pendulum damper and deterioration of reliability of the centrifugal pendulum damper by high-speed rotation. A power transmission apparatus with a centrifugal pendulum damper includes: a centrifugal pendulum damper coupled to an input shaft through a speed-increasing mechanism configured to increase speed of rotation of the input shaft; and an engagement/disengagement mechanism capable of realizing and cutting off power transmission from the input shaft to the centrifugal pendulum damper.
