VIBRATION CONTROL DEVICE

PROBLEM TO BE SOLVED: To provide a vibration control device capable of damping both of two kinds of vibration of different vibration frequencies. SOLUTION: This vibration control device 10 is provided with a circular mounting fitting 11 like a flat plate, a mass fitting 13 opposing to its one plane across predetermined distance and having a circular column shape, and a stopper fitting 14 composed of a rubber elastic body 17 connecting the mounting fitting 11 with the mass fitting 13 elastically and having a substantially circular column shape and a flange part 16 fixed on a side wall of the mass fitting 13, extending on a mounting fitting 11 side, and extending outward in the radial direction on a tip side to oppose to the mounting fitting 11. A rubber covered part 18 including an annular rubber protruding part 19 is bonded on a face where the flange part 16 opposes to the mounting fitting 11. This vibration control device serves also as a first vibration damping mechanism for damping vibration of high frequency and a second vibration damping mechanism for damping vibration of low frequency.
