PROBLEM TO BE SOLVED: To provide a revolution adaptive vibration reducer in which supporting of an inertia block does not cause impermissible noise in the start and the end of the rotational movement. SOLUTION: A revolution adaptive vibration reducer is composed of a hub 1 capable of being rotated around a rotary shaft 3, and a plurality of inertia blocks 2 to follow the rotational movement 4 and able to be rotated around the rotary shaft separated from the rotary shaft 3, respective inertia blocks 2 are supported to the hub part 1 by two pins 5 extending in parallel with the rotary shaft 3 at a distance in the circumferential direction, the pins 5 can be rolled on curved passages 6 provided with outlines releasing into a U shape in the direction of the rotary shaft 3 in the section of the hub part 1 and into a U shape in the reverse direction in the section of the inertia block 2, and the pins 5 are guided by guiding passages 7 on the opposite side to respective curved passages 6. |
