The invention provides a cylindrical anti-vibration device with a novel structure, which can easily mount an outer cylindrical member on a holder and can realize a stable mounting state. In a cylindrical anti-vibration device (10), an outer cylindrical member (14) is provided with: a cylindrical section (20) that is press-fitted into a mounting hole (60); a plurality of flange-shaped sections (26, 26) that protrude to the outer periphery at one axial end of the cylindrical section and overlap with one axial opening end surface of the mounting hole; and a plurality of hooking parts (28, 28) protruding to the outer circumference at the other axial end of the cylindrical part and locked to the other axial opening end surface of the mounting hole, the hooking parts being provided at positions corresponding to a plurality of recessed holes (38, 38) penetrating the main body rubber elastic body (16) in the axial direction in the circumferential direction. The flange-shaped portion is provided at a position different from that of the hook portion in the circumferential direction, and a biasing rubber (54) is affixed to an overlapping surface of the flange-shaped portion that overlaps the opening end surface of the mounting hole.

    本发明提供一种新型结构的筒形防振装置,能够容易地将外筒构件安装于保持件而能够实现稳定的安装状态。一种筒形防振装置(10),外筒构件(14)具备:筒状部(20),其压入于装配用孔(60);多个凸缘状部(26、26),其在筒状部的轴向一方的端部向外周突出并与装配用孔的轴向一方的开口端面重叠;以及多个钩挂部(28、28),其在筒状部的轴向另一方的端部向外周突出并与装配用孔的轴向另一方的开口端面卡止,钩挂部设置于在周向上与将主体橡胶弹性体(16)沿轴向贯通的多个凹缺孔(38、38)对应的位置,凸缘状部设置于与钩挂部在周向上不同的位置,在凸缘状部的与装配用孔的开口端面重叠的重叠面固接有施力橡胶(54)。
