To provide a vibration control system with a novel structure, which can be easily attached to a vibration-control object member.SOLUTION: A plate-like bracket metal part 12 includes a first extended part 22 and a second extended part 30 on both sides of an attachment part 18, and edge flanges 34 are standing on both edges of the attachment part 18. In the first extended part 22, the edge flange 34 continues from the attachment part 18, and a first dynamic damper 14 having a pair of support rubber elastic part 38, 38 and a mass member 36 are provided between a pair of standing walls 26, 26. A standing support part 32 stands at the edge of the second extended part 30, and the edge flange 34 continues from the attachment part 18 along an entire length of the second extended part 30 including the standing support part 32. Also, a second dynamic damper 16 that elastically connects an inner shaft member 54 and an outer mass member 56 by a body rubber elastic part 58 is attached to the standing support part 32.SELECTED DRAWING: Figure 1 【課題】制振特性の調節自由度を大きく得つつ、制振対象部材に対して容易に取り付けることができる、新規な構造の制振装置を提供すること。【解決手段】板状のブラケット金具１２は、取付部１８の両側に第一の延出部２２と第二の延出部３０を備えており、取付部１８の両縁部に縁フランジ３４が立ち上がっている。第一の延出部２２において、縁フランジ３４が取付部１８から連続していると共に、一対の支持ゴム弾性体３８，３８とマス部材３６を有する第一のダイナミックダンパ１４が、一対の立上壁２６，２６の間に設けられている。第二の延出部３０の端部には立上支持部３２が立ち上がっており、縁フランジ３４が取付部１８から立上支持部３２を含む第二の延出部３０の全長に亘って連続していると共に、インナ軸部材５４とアウタマス部材５６を本体ゴム弾性体５８で弾性連結した第二のダイナミックダンパ１６が立上支持部３２に取り付けられている。【選択図】図１
