To provide a vibration isolator capable of temporarily fixing a stopper easily while suppressing an increase in the number of components and the number of man-hours.SOLUTION: A vibration isolator 12 includes: an outer cylinder 18; an inner cylinder 20; a vibration isolating rubber 22 interposed between these cylinders; a stopper 30 attached to the vibration isolating rubber 22 on a device lower end side of the inner cylinder 20, which is formed substantially into a disc-shape in its whole shape, and whose outer edge part is curved toward a vibration isolating rubber 22 side; a projection part 40 formed along an axial direction of the inner cylinder 20 on a side where the stopper 30 is attached of the vibration isolating rubber 22, which projects from a device lower end side of the inner cylinder 20; a protrusion 42 extending along a radial direction from the vibration isolating rubber 22 in the projection part 40; and an engagement part 34 formed so as to engage with the protrusion 42 in the outer edge part of the stopper 30.SELECTED DRAWING: Figure 2

    【課題】部品点数と作業工数の増加を抑制した上でストッパを簡易に仮留めすることができる防振装置を提供する。【解決手段】防振装置12を、外筒18と、内筒20、これらの間に介在する防振ゴム22と、内筒20の装置下端側において防振ゴム22に取り付けられ、全体形状が略円板状に形成されると共に外縁部が防振ゴム22の側へ向けて湾曲されたストッパ30と、防振ゴム22のストッパ30が取り付けられる側において、内筒20の軸方向に沿って形成されると共に内筒20の装置下端側から突出された突出部40と、突出部40において防振ゴム22から径方向に沿って延在された突起42と、ストッパ30の外縁部に突起42と係合可能に形成された係合部34と、を含んで構成する。【選択図】図2
