To provide a vibration isolating/damping device capable of equalizing displacements of two dampers disposed in series.SOLUTION: A vibration isolating/damping device comprises: a first damping mechanism 2 and a second damping mechanism 3 (damping mechanisms) in which a first rotary viscous damper 4 to be connected to an upper structure 12 and a second rotary viscous damper 5 which is connected to a lower structure 13 and of which the damping characteristic is equal to that of the first rotary viscous damper 4 are coaxially connected. Any one of a first ball screw 45 and a second ball screw 55 is a right screw and the other is a left screw. A first outer cylinder 41 and a second outer cylinder 51 are connected, and a first inner cylinder 42 and a second inner cylinder 52 are connected. A first ball nut 44 and a second ball nut 54 are connected via the first inner cylinder 42 and the second inner cylinder 52 which are connected with each other.SELECTED DRAWING: Figure 2
【課題】直列に配置した２つのダンパーの変位を同一にすることができる免制振装置を提供する。【解決手段】上部構造体１２に連結される第１回転式粘性ダンパー４と、下部構造体１３に連結され第１回転式粘性ダンパー４と減衰特性が等しい第２回転式粘性ダンパー５と、が同軸に連結された第１減衰機構２および第２減衰機構３（減衰機構）を有し、第１ボールねじ４５および第２ボールねじ５５は、いずれか一方が右ねじであり、他方が左ねじであり、第１外筒４１と第２外筒５１とが連結されるとともに、第１内筒４２と第２内筒５２とが連結され、互いに連結された第１内筒４２および第２内筒５２を介して第１ボールナット４４と第２ボールナット５４とが連結されている。【選択図】図２
