PURPOSE:To meet required characteristics by coupling and supporting a pair of electrodes respectively to/on first and second supporting members and placing an elastic rubber coupling body at a joint to an electrode on at least one supporting member at vibration input side. CONSTITUTION:A first electrode 36 is fixed through an elastic rubber coupling body 68 to an upper side supporting metal 10 at vibration input side to constitute a sub-vibration system (vibration absorber) for the supporting metal 10. In other word, the electrode 36 constitute a mass member together with fixing metals 62, 64 and a guide tube 50 so as to constitute a vibration system where the elastic rubber coupling body 68 is employed as a spring and fixed to the upper side supporting metal 10. When inherent vibration in expanding/shrinking direction of the elastic rubber body 68 is tuned to a vibration frequency zone desired for isolation of vibration, vibration in a specific frequency zone in the direction of mounting shaft can be absorbed and suppressed effectively through such dynamic vibration absorber. |
