VIBRATION REDUCTION DEVICE AND BASE ISOLATION STRUCTURE
PROBLEM TO BE SOLVED: To provide a vibration reduction device and a base isolation structure including the vibration reduction device realizing a superior vibration reducing performance to enable a displacement to be efficiently and positively restricted while absorbing vibration energy acted on a building.SOLUTION: This invention relates to a vibration reducing device A for reducing a relative vibration between the two members that vibrate from each other comprising: a cylinder 1 arranged with one end 1a being connected to one member; a piston 5 for defining an inner part of the cylinder 1 into a first partition chamber 3 and a second partition chamber 4; a piston rod 2 connected at one end 2b to the piston 5, extended outside in a direction toward an axial line O1 of the cylinder 1, and connected to the other member at the other end 2a to be arranged; a connecting pipe 6 communicating the first partition chamber 3 and the second partition chamber 4; and an orifice 7 arranged at the connecting pipe 6, and working fluid S is charged in the first partition chamber 3, the second partition chamber 4, and the connecting pipe 6.
【課題】優れた振動低減性能を発揮して建物に作用した振動エネルギーを吸収しつつ効率的且つ確実に変位を抑制することが可能な振動低減装置及びこれを備えた免震構造物を提供する。【解決手段】相対振動する二部材の間の相対振動を低減させるための振動低減装置Ａであって、一端１ａを一方の部材に接続して配設されるシリンダー１と、シリンダー１の内部を第１隔室３と第２隔室４に区画するピストン５と、ピストン５に一端２ｂを接続してシリンダー１の軸線Ｏ１方向外側に延設され、他端２ａを他方の部材に接続して配設されるピストンロッド２とを備え、且つ、第１隔室３と第２隔室４を連通させる連結管６と、連結管６に設けられたオリフィス７とを備え、第１隔室３と第２隔室４と連結管６とに作動流体Ｓを充填して構成する。【選択図】図１
