CENTRIFUGAL PENDULUM TYPE VIBRATION ABSORBER

Japanese Patent JP2015224762

A

PROBLEM TO BE SOLVED: To provide a centrifugal pendulum type vibration absorber which can favorably attenuate the vibration of a rotating element even if a degree of vibration transmitted to the rotating element from a control device is changed.SOLUTION: A centrifugal pendulum type vibration absorber 20 includes: a plurality of first mass bodies 21 which are connected to a driven member 15 of a damper mechanism so as to oscillate around a pendulum fulcrum PF1; and a plurality of second mass bodies 22 which are connected to the driven member 15 so as to oscillate around a pendulum fulcrum PF2. First annular mass bodies 25 are connected to the plurality of first mass bodies 21 so as to oscillate around a rotation center RC of the driven member 15 accompanied by the oscillation of the first mass bodies 21, second annular mass bodies 26 are connected to the plurality of second mass bodies 22 so as to oscillate around the rotation center RC accompanied by the oscillation of the second mass bodies 22, and the first mass bodies 21 connected to the first annular mass bodies 25 and the second mass bodies 22 connected to the second annular mass bodies 26 have different vibration degrees.
