To provide an antivibration device for suppressing an increase in the size.SOLUTION: In an outside mounting member 11, a lateral opening 11a is formed which passes through the outside mounting member 11 in the thickness direction and communicates through a second restriction passage 32 with a second pressure receiving liquid chamber 27. The lateral opening 11a is covered through the outside of the outside mounting member 11 with a second diaphragm 31. Between the second diaphragm 31 and the outer peripheral face of the outside mounting member 11, a second sub liquid chamber 29 is defined which communicates through the lateral opening 11 and the second restriction passage 32 with the second pressure receiving liquid chamber 27.SELECTED DRAWING: Figure 2
【課題】大型化を抑える。【解決手段】外側取付部材11に、この外側取付部材11を厚さ方向に貫き、かつ第2制限通路32を通して第2受圧液室27に連通する側方開口11aが形成され、側方開口11aが、外側取付部材11の外側から第2ダイヤフラム31に覆われて、この第2ダイヤフラム31と外側取付部材11の外周面との間に、第2受圧液室27に側方開口11aおよび第2制限通路32を通して連通する第2副液室29が画成されている。【選択図】図2
