PROBLEM TO BE SOLVED: To provide a vibration control device in which workability of work for fixing an upper transmission member to an upper beam is improved.SOLUTION: An vibration damping device 11 includes an upper transmission member 18 to which horizontal vibration of an upper beam 1A is inputted, a lower transmission member 13 to which horizontal vibration of a lower beam 1B is input, a damper 28 which is provided between the upper transmission member 18 and the lower transmission member 13 and buffers a relative displacement between the upper transmission member 18 and the lower transmission member 13. An upper attachment member 22 is attached to a lower surface 1 A1 of the upper beam 1A. The upper transmission member 18 is fixed to the upper beam 1A via an upper attachment member 22 by a screw 24. A temporary attachment part 25 capable of fixing the upper transmission member 18 to the upper attachment member 22 is provided in the upper attachment member 22 and the upper transmission member 18 in a state before being fastened by a screw 24.SELECTED DRAWING: Figure 1 【課題】上部伝達部材を上梁に固定するときの作業の作業性を向上した制震装置を提供する。【解決手段】制震装置１１は、上梁１Ａの水平方向の振動が入力される上部伝達部材１８と、下梁１Ｂの水平方向の振動が入力される下部伝達部材１３と、上部伝達部材１８と下部伝達部材１３との間に設けられ、上部伝達部材１８と下部伝達部材１３との相対変位を緩衝するダンパ２８とを備えている。上梁１Ａの下面１Ａ１には、上部取付部材２２が取付けられている。上部伝達部材１８は、ねじ２４により上部取付部材２２を介して上梁１Ａに固定されている。上部取付部材２２および上部伝達部材１８には、ねじ２４により締結する前の状態で、上部取付部材２２に対し上部伝達部材１８を固定可能な仮固定部２５が設けられている。【選択図】図１
