To provide a cylindrical vibration damper with a bracket of a novel structure, which can improve functional compliment of an outer cylinder member and a cylindrical portion of an outer side bracket, and simultaneously can reduce weight.SOLUTION: A cylindrical vibration damper 10 with a bracket includes a cylindrical mount body 12 in which an inner member 16 and an outer cylinder member 18 are coupled by a body rubber elastic body 20, and an outer side bracket 14 that has a cylindrical portion 34 in which the outer cylinder member 18 is pressed and fixed. The cylindrical mount body 12 is partially provided with an axially orthogonal stopper 52 that limits the relative displacement amount in an axial orthogonal direction of the inner member 16 and the outer cylinder member 18, in a circumferential direction. On the other hand, in the outer side bracket 14, a notch portion 38 is provided at a part deviated from the axially orthogonal stopper 52 in the circumferential direction at an axial end portion of the cylindrical portion 34. The axial length of the cylindrical portion 34 is shortened by the notch portion 38, and the outer cylinder member 18 is exposed to an outer periphery through the notch portion 38.SELECTED DRAWING: Figure 1
【課題】アウタ筒部材とアウタ側ブラケットの筒状部との機能的な相互補完を向上させることができると共に、軽量化も同時に達成することができる、新規な構造のブラケット付き筒型防振装置を提供すること。【解決手段】インナ部材16とアウタ筒部材18とが本体ゴム弾性体20で連結された筒型マウント本体12と、アウタ筒部材18が圧入固定された筒状部34を有するアウタ側ブラケット14とを、含むブラケット付き筒型防振装置10において、筒型マウント本体12には、インナ部材16とアウタ筒部材18との軸直角方向の相対変位量を制限する軸直ストッパ52が周方向で部分的に設けられている一方、アウタ側ブラケット14には、筒状部34の軸方向端部において軸直ストッパ52を周方向に外れた部分に切欠部38が設けられており、筒状部34の軸方向長さが切欠部38によって短くされて、アウタ筒部材18が切欠部38を通じて外周へ露出している。【選択図】図1
