To provide a vibration control device with a simple structure excellent in vibration control performance and durability.SOLUTION: A vibration control device of this invention includes an elastic body unit, a pair of fastening members, and a holding member. The elastic body unit has a structure in which a first elastic body composed of a spherical rubber and a second elastic body composed of a plurality of spherical rubbers arranged along a direction of going around the first elastic body are integrally formed. The pair of the fastening member fastens the elastic body unit from a direction along a center axis of the going around direction. The holding member elastically holds a peripheral end of the pair of the fastening members from the outer side.SELECTED DRAWING: Figure 2 【課題】防振性能及び耐久性に優れた簡素な構造の防振装置を提供する。【解決手段】本発明の防振装置は、弾性体ユニット、一対の挟持部材、及び保持部材を備えている。弾性体ユニットは、球状のゴムからなる第１の弾性体と前記第１の弾性体を周回する方向に沿って配列された複数の球状のゴムからなる第２の弾性体とが一体化された構造を有する。一対の挟持部材は、弾性体ユニットを前記周回の中心軸に沿った方向から挟持する。保持部材は、一対の挟持部材の周縁部を外側から弾性的に保持する。【選択図】図２
