ABSTRACT:
A dynamic vibration absorber includes a movable weight portion, and a movable portion magnet assembly provided for the movable weight portion. The movable portion magnet assembly includes a magnet train having a plurality of cylindrical magnets disposed coaxially in such a manner that adjacent cylindrical magnets have different adjacent magnetic poles. A fixed portion is provided in opposed relation to the movable weight portion and a fixed portion magnet train is provided on the fixed portion and includes a plurality of magnets having magnetic poles different, in a stationary state, from opposed magnetic poles of the cylindrical magnets. The movable weight portion is preferrably disposed in a vessel. A magnetic damper is further provided, which has a plurality of conductor plates mounted on an outer peripheral surface of the movable weight portion, and a plurality of yokes are secured to an inner surface of the peripheral side portions of the cylindrical vessel at portions corresponding to the conductor plates. Each of the yokes have a pair of yoke portions facing each other, and a pair of magnets are provided on the facing surfaces of the paired yoke portions with a gap therebetween into which the corresponding conductor plates are inserted.
