To provide a cylindrical vibration damper with a bracket of a novel structure, which can improve functional complement of an inner cylinder member and a bracket fixing portion.SOLUTION: A cylindrical vibration damper 10 with a bracket includes a cylindrical mount body 12 in which an inner cylinder member 18 and an outer cylinder member 20 are coupled by a body rubber elastic body 22, and an inner side bracket 14 that has a fixing portion 36 pressed in the inner cylinder member 18. The cylindrical mount body 12 is provided with an axially orthogonal stopper 60 that limits the relative displacement amount in an axial orthogonal direction of the inner cylinder member 18 and the outer cylinder member 20. On the other hand, a press-in tip end position P to the inner cylinder member 18 at the fixing portion 36 of the inner side bracket 14 is set at a middle in an axial direction in the inner cylinder member 18, and reaches an area in which the axially orthogonal stopper 60 is provided.SELECTED DRAWING: Figure 1 【課題】インナ筒部材とブラケット固定部との機能的な相互補完を向上させることができる、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】インナ筒部材１８とアウタ筒部材２０とが本体ゴム弾性体２２で連結された筒型マウント本体１２と、インナ筒部材１８へ圧入された固定部３６を有するインナ側ブラケット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、インナ筒部材１８とアウタ筒部材２０との軸直角方向の相対変位量を制限する軸直ストッパ６０が設けられている一方、インナ側ブラケット１４の固定部３６におけるインナ筒部材１８への圧入先端位置Ｐが、インナ筒部材１８における軸方向の途中に設定されており、且つ、軸直ストッパ６０が設けられた領域にまで達している。【選択図】図１
