To provide a cylindrical vibration isolator having a novel structure which can set an attachment face to a connection objective member at an inner shaft member side at a high degree of freedom while satisfying a requirement property such as a spring characteristic and durability.SOLUTION: In a cylindrical vibration isolator 10 in which an inner shaft member 16 and an outer cylinder member 18 are arranged in an outside/inside insertion state while separating from each other in a radial direction, and connected to each other by a main body rubber elastic body 20, an attachment face 26 expanding in an axial direction at an external peripheral face of an end part in the axial direction protruding from the main body rubber elastic body 20 is formed at the inner shaft member 16, an attachment hole 32 which is opened at the attachment face 26 is formed, an attachment member 14 is arranged which is assembled toward the attachment face 26 from a sideway with respect to the end part of the inner shaft member 16 in the axial direction, a cylindrical fixing part 54 protruding to the attachment face 26 side of the inner shaft member 16, and pressure-fixed to the attachment hole 32 is formed at the attachment member 14, and an attachment face 50 to a connection objective member 76 is formed at a side opposite to the attachment face 26 of the attachment member 14.SELECTED DRAWING: Figure 3
【課題】ばね特性や耐久性等の要求性能を満たしつつ、インナ軸部材側の連結対象部材への取付面を大きな自由度で設定できる、新規な構造の筒型防振装置を提供する。【解決手段】インナ軸部材16とアウタ筒部材18とが、互いに径方向に離隔して内外挿状態で配されて本体ゴム弾性体20で連結された筒型防振装置10であって、インナ軸部材16には、本体ゴム弾性体20から突出した軸方向端部の外周面において軸方向に広がる装着面26が形成されていると共に、装着面26に開口する取付孔32が形成されている一方、インナ軸部材16の軸方向端部に対して装着面26に向けて側方から組み付けられた取付用部材14を有しており、取付用部材14にはインナ軸部材16の装着面26側に突出して取付孔32へ圧入固定される筒状固定部54が形成されていると共に、取付用部材14における装着面26と反対側には連結対象部材76への取付面50が形成されている。【選択図】図3
