A centrifugal pendulum damper for effectively suppressing torsional vibrations resulting from torque pulse. The centrifugal pendulum damper comprises: a rotary member rotated by a torque; an inertial member that rotates relatively to the rotary member; a chamber formed on the inertial member; and a rolling member held partially in the chamber while being allowed to oscillate therein, and held partially by the rotary member while being allowed to move radially. A raceway surface on which the rolling member rolls is formed in the chamber in such a manner that a curvature radius of an orbit of a gravity center of the rolling member oscillating along the raceway surface is increased with an increase in an oscillation angle of the rolling member.
