To provide a new fluid sealed type vibration control device which enables an outer cylinder metal fitting having an abnormal shape in an axial view to be fitted into a bracket member stably.SOLUTION: In a hanging fluid sealed type vibration control device 10, an outer cylinder metal fitting 20 has a straight part 34 and a taper part 36. The outer cylinder metal fitting 20 is provided with a caulking piece 40 fixedly caulked to a caulking part 50. A thickness dimension of the caulking piece 40 is larger than that of the caulking part 50. The straight part 34 is formed in a long cylindrical shape having a pair of two-face width parts 42 and a pair of curved parts 44. The hanging fluid sealed type vibration control device 10 is further provided with a bracket member 76 into which the straight part 34 is fitted. The bracket member 76 is spaced apart from the caulking piece 40 in a downward direction and spaced apart from the taper part 36. A press-in margin in the two-face width part 42 is larger than that in the curved part 44. A circumferential length dimension C of the two-face width part 42 is larger than or equal to one-fourth times of a long diameter dimension L of the straight part 34.SELECTED DRAWING: Figure 3

    【課題】軸方向視が異形状とされたアウタ筒金具をブラケット部材に対して安定して圧入することのできる、新規な流体封入式防振装置を提供する。【解決手段】吊下型の流体封入式防振装置10において、アウタ筒金具20はストレート部34とテーパ部36とを有しており、アウタ筒金具20には、かしめ部50に対してかしめ固定されるかしめ片40が設けられており、かしめ片40の厚さ寸法がかしめ部50よりも大きくされており、ストレート部34は一対の2面幅部42と一対の湾曲部44とを有する長円筒形状とされており、ストレート部34が圧入されるブラケット部材76が設けられており、ブラケット部材76は、かしめ片40に対して下方に離隔していると共にテーパ部36に対して離隔しており、2面幅部42における圧入代が湾曲部44よりも大きくされており、2面幅部42の周方向長さ寸法Cがストレート部34の長径寸法Lの1/4倍以上とされている。【選択図】図3
