To prevent deformation of an elastic support part due to settling of an elastic material and misalignment of a rotary machine while securing vibration control performance.SOLUTION: A vibration control system 50 includes: a support base 51 for supporting a speed reducer 20; and multiple vibration control devices 60 for supporting the support base 51. Each of the multiple vibration control devices 60 includes at least one of: an elastic support part for supporting the support base 51; and a slide support part for supporting the support base 51, restricting a strain amount of the elastic support part in a longitudinal direction to a certain amount and capable of laterally sliding in accordance with lateral vibration of the support base 51.SELECTED DRAWING: Figure 2 【課題】防振性能を確保しつつ、弾性材のへたりによる弾性支持部の変形および回転機械の芯ずれを防止する。【解決手段】防振システム５０は、減速機２０を支持する支持架台５１と、支持架台５１を支持する複数の防振装置６０と、を備え、複数の防振装置６０の各装置が、支持架台５１を支持する弾性支持部、及び、支持架台５１を支持し、弾性支持部の縦方向のたわみ量を一定量までに制限すると共に、支持架台５１の横振れに応じて横滑り可能な滑り支持部のうち、少なくともいずれか一方を備える。【選択図】図２
