To provide a cylindrical vibration isolator having a novel structure which is reducible in a size and weight by setting a rubber volume of a main body rubber elastic body according to an input load.SOLUTION: In a cylindrical vibration isolator 60 having a structure in which a cylindrical main-body rubber elastic body 42 is arranged at an internal periphery of a cylindrical part 22 of an outer member 12, the main-body rubber elastic body 42 comprises a rubber long-length part 48 whose dimension in an axial direction is large, and a rubber short-length part 50 whose dimension in the axial direction is small in positions which are displaced from each other in a circumferential direction. The cylindrical part 22 of the outer member 12 is set as an outer long-length part 24 whose dimension in the axial direction of a region corresponding to the rubber long-length part 48 in the circumferential direction is large, and an outer short-length part 26 whose dimension in the axial direction of a region corresponding to the rubber short-length part 50 in the circumferential direction is small.SELECTED DRAWING: Figure 6
【課題】本体ゴム弾性体のゴムボリュームを入力荷重に応じて設定して小型化や軽量化を図ることができる、新規な構造の筒形防振装置を提供する。【解決手段】筒状の本体ゴム弾性体42がアウタ部材12の筒状部22の内周に配された構造を有する筒形防振装置60であって、本体ゴム弾性体42は、軸方向寸法が大きいゴム長尺部48と、軸方向寸法が小さいゴム短尺部50とを、周方向で相互にずれた位置に備えており、アウタ部材12の筒状部22は、周方向におけるゴム長尺部48と対応する部位が軸方向寸法が大きいアウタ長尺部24とされており、周方向におけるゴム短尺部50と対応する部位が軸方向寸法が小さいアウタ短尺部26とされている。【選択図】図6
