To provide a rotational inertia mass damper capable of changing a viscous damping effect, while securing symmetric properties in a case when moving directions of a piston are different, without requiring supply of electric power.SOLUTION: A rotational inertia mass damper 1 includes: a cylinder 2 filled with a working fluid HF; a piston 3 slidable in the cylinder 2 and partitioning the inner space of the cylinder into first and second fluid chambers 2d, 2e; first and second communication passages 5, 6 communicating with the first and second fluid chambers 2d, 2e in parallel with each other; a gear motor M disposed in the first communication passage 5; a rotary mass 21 rotatively driven by the gear motor M; opening/closing valves 41, 41 disposed in the second communication passage 6 and opened when a fluid chamber pressure reaches a first prescribed pressure; a pressure introduction passage 42 which is connected between the opening/closing valves 41, 41 of the second communication passage 6, and into which the fluid chamber pressure is introduced accompanied with the opening of the opening/closing valve 41; and adjustment valves 8, 8 disposed at both sides of the gear motor M and adjusting the opening of the first communication passage 5 by the introduced fluid chamber pressure.SELECTED DRAWING: Figure 1
【課題】電力の供給を必要とせずに、ピストンの移動方向が異なる場合の対称性を確保しながら、粘性減衰効果を変更できる回転慣性質量ダンパを提供する。【解決手段】本発明の回転慣性質量ダンパ１は、作動流体ＨＦが充填されたシリンダ２と、シリンダ２内を摺動自在で、第１及び第２流体室２ｄ、２ｅに区画するピストン３と、第１及び第２流体室２ｄ、２ｅに連通する互いに並列の第１及び第２連通路５、６と、第１連通路５に設けられた歯車モータＭと、歯車モータＭで回転駆動される回転マス２１と、第２連通路６に設けられ、流体室圧力が第１所定圧に達したときに開弁する開閉弁４１、４１と、第２連通路６の開閉弁４１、４１の間に接続され、開閉弁４１の開弁に伴って流体室圧力が導入される圧力導入路４２と、歯車モータＭの両側に設けられ、導入された流体室圧力によって、第１連通路５の開度を調整する調整弁８、８と、を備える。【選択図】図１
