To provide a vibration prevention device with a new structure capable of restraining a body rubber outer member from being detached from a drawing metal fitting, at the time of fixing by reducing diameters of the body rubber outer member and the drawing metal fitting constituting a second mounting member.SOLUTION: In a vibration prevention device 10, a second mounting member 18 includes a body rubber outer member 34 having a first tubular part 36 affixed to an outer peripheral end of a body rubber elastic body 20, and a drawing metal fitting 54 having a second tubular part 54 mounted to the first tubular part 36 of the body rubber outer member 34 under an extrapolation condition. The first tubular part 36 of the body rubber outer member 34 is inserted into the second tubular part 54 of the drawing metal fitting 54 in an axial direction, and the second tubular part 54 is fitted with an outer periphery of the first tubular part 36 by diameter-reduction processing. The fitting portion of the first tubular part 36 and the second tubular part 54 comprises tapered parts 42, 66 whose diameter gets smaller toward a detachment direction opposite to a direction, in which the first tubular part 36 is inserted into the second tubular part 54.SELECTED DRAWING: Figure 1

    【課題】第二の取付部材を構成する本体ゴムアウタ部材と絞り金具の縮径による固定に際して、本体ゴムアウタ部材の絞り金具からの抜けを抑えることができる、新規な構造の防振装置を提供すること。【解決手段】防振装置10であって、第二の取付部材18は、本体ゴム弾性体20の外周端部に固着される第一の筒状部36を備えた本体ゴムアウタ部材34と、本体ゴムアウタ部材34の第一の筒状部36に外挿状態で取り付けられる第二の筒状部54を備えた絞り金具54とを含んで構成されており、本体ゴムアウタ部材34の第一の筒状部36が絞り金具54の第二の筒状部54に対して軸方向に挿入されて、第二の筒状部54が縮径加工によって第一の筒状部36の外周面に嵌着されており、それら第一の筒状部36と第二の筒状部54の嵌着部分は、第一の筒状部36の第二の筒状部54への挿入方向と反対の抜け方向に向けて小径となるテーパ部42,66を備えている。【選択図】図1
