PROBLEM TO BE SOLVED: To provide a vibration isolation device and a vibration isolation unit capable of reducing noise or the like caused by collision when holding the vibration isolation device with a member by inserting the vibration isolation device from a side surface of the member.SOLUTION: A vibration isolation device 10 of this invention, incudes: a cylindrical outside attachment member 11; an inside attachment member 12 connected to one of either a vibration generating part or a vibration receiving part; an elastic body 13 for elastically connecting the outside attachment member 11 and the inside attachment member 12; and a diaphragm 20 forming a part of a wall surface of a liquid chamber Stogether with the elastic body 13, and a part 20b of the diaphragm 20 works as a stopper 21 protruding to outer side of a radial direction relative to an outer surface of the outside attachment member 11. A vibration isolation unit 1 of this invention has the vibration isolation device 10, and a bracket 40 which is a member having a holding part for holding the vibration isolation device 10 and connected to the other of either the vibration generating part or the vibration receiving part, and the bracket 40 has a contact part 42 with which the stopper 21 is brought into contact.SELECTED DRAWING: Figure 2

    【課題】部材の側面から防振装置を挿入することにより当該防振装置を前記部材で保持する場合に、衝突により生じる異音等を低減させることができる、防振装置、および、防振ユニットを提供する。【解決手段】本発明の防振装置10は、筒状の外側取付部材11と、振動発生部及び振動受部のいずれか一方に連結される内側取付部材12と、外側取付部材11及び内側取付部材12を弾性的に連結する弾性体13と、弾性体13とともに液室S2の壁面の一部を形成するダイヤフラム20と、を有し、ダイヤフラム20の一部20bを、外側取付部材11の外面よりも径方向外側に突出するストッパ部21としたことを特徴とする。本発明の防振ユニット1は、防振装置10と、防振装置10を保持する保持部を有して前記振動発生部及び前記振動受部のいずれか他方に連結される部材ブラケット40と、を有し、さらに、ブラケット40は、ストッパ部21を接触させる接触部42を有することを特徴とする。【選択図】図2
