PROBLEM TO BE SOLVED: To provide a vibration isolator, which can reduce a vibration of a small frequency number and can be installed through simple work, and may secure a function as a vibration isolator even when large force has been input.SOLUTION: A vibration isolator 1 includes: a laminated body 10 having a rubber plate 11 and a hard plate 12; a top plate 21 and a bottom plate 26 disposed to sandwich the laminated body 10 in an axial line direction; a lower support part 27 provided on the bottom plate 26 so as to extend outward the axial line direction on one side of the laminated body 10 in the axial line direction, for restricting displacement of the one side of the laminated body 10 by a prescribed amount or more in a direction orthogonal to the axial line direction; and an upper support part 22 provided on the top plate 21 so as to extend inward the axial line direction on the other side of the laminated body 10 in the axial line direction. The lower support part 27 and the upper support part 22 are provided to overlap with each other when seen from the direction orthogonal to the axial line direction.SELECTED DRAWING: Figure 3
【課題】低い振動数の振動を低減することができ且つ簡単な工事によって設置可能な防振装置において、大きな力が入力された場合でも、防振装置としての機能を確保可能な構成を得る。【解決手段】防振装置１は、ゴム板１１及び硬質板１２を有する積層体１０と、積層体１０を軸線方向に挟み込むように配置された天板２１及び底板２６と、底板２６に、積層体１０における前記軸線方向の一方側の外方に該軸線方向に延びるように設けられ、積層体１０の前記一方側が前記軸線方向と直交する方向に所定量以上、変位することを規制する下側支持部２７と、天板２１に、積層体１０における軸線方向の他方側の内方に該軸線方向に延びるように設けられた上側支持部２２とを備える。下側支持部２７及び上側支持部２２は、前記軸線方向と直交する方向から見て、重なるように設けられている。【選択図】図３
