To reduce a swing range of a mass body to realize a compact skeleton while securing vibration control performance.SOLUTION: A pendulum type vibration control device 10A comprises: a support frame 20; a flexible hanging material 25 provided so as to extend downward from the support frame 20; a mass body 30 that is suspended from the hanging material 25, and is swingably provided with respect to the support frame 20; an attenuation device 40 whose one end is attached to the mass body 30 and other end is attached to the support frame 20; and a swing limit unit 50 that is provided at an interval from the hanging material 25 so as to be immovable relative to the support frame 20 in a middle part of the hanging material 25, and with which the hanging material 25 is brought into contact when the mass body 30 swings, to limit a swing range above the hanging material 25.SELECTED DRAWING: Figure 1 【課題】制振性能を確保しつつ、質量体の揺動範囲を小さくして、躯体をコンパクトに実現する。【解決手段】振り子型の制振装置１０Ａは、支持フレーム２０と、支持フレーム２０から下方側に向かって延びるように設けられた、可撓性を有する吊材２５と、吊材２５に吊り下げられ、支持フレーム２０に対して揺動自在に設けられた質量体３０と、質量体３０に一方端が取り付けられ、かつ支持フレーム２０に他方端が取り付けられる減衰装置４０と、吊材２５の中間部において、支持フレーム２０に対して相対移動不能に、吊材２５から間隔をあけて設けられ、質量体３０が揺動したときに吊材２５が接触して、吊材２５のより上側の揺動範囲を制限する、揺動制限部５０と、を備える【選択図】図１
