<P>PROBLEM TO BE SOLVED: To provide a pendulum type dynamic vibration reducer capable of improving the effect as the dynamic vibration reducer, by restraining generation of an abnormal sound by regulating irregular motion of a pendulum when starting a rotary member and when rotating at a low speed. Ž<P>SOLUTION: The pendulum 20 is rockably arranged along a guide groove 18 by loosely fitting a pendulum 20 side pin 22 to the guide groove 18 arranged on the rotary member side, and a stopper 26 energized in the mutually approaching direction sandwiches the pin 22 from both sides in the rocking direction. A piston is arranged for moving in the radial direction of the rotary member by receiving centrifugal force of the rotary member, and this piston and the stopper 26 are connected by a link mechanism, and when the centrifugal force acting on the piston becomes larger than a preset value, the stopper 26 is moved in the direction for separating from the pin 22 by overcoming energizing force.
