To provide a fluid-sealed vibration control device of a new structure, capable of achieving high fluid sealability between a main body elastic body and a partitioning member axially pressed against each other.SOLUTION: In a fluid-sealed vibration control device 10, an axial end portion of a main body rubber elastic body 16 is fastened to an inner peripheral face of a cylindrical portion 22 of an outer member 14, the axial end portion of the main body rubber elastic body 16 includes a seal rubber portion 30, a partitioning member 32 disposed at an inner peripheral side of the cylindrical portion 22 of the outer member 14 is pressed against an axial end face of the seal rubber portion 30 on a pressing seal face 56 positioned at an outer peripheral edge portion of the axial end face, and a seal projection 54 of the partitioning member 32 projected outward in an axial direction on the pressing seal face 56 is more strongly pressed against the axial end face of the seal rubber portion 30, so that the seal rubber portion 30 and the partitioning member 32 are fluid-sealed in the axial direction.SELECTED DRAWING: Figure 1
【課題】軸方向で相互に押し付けられる本体ゴム弾性体と仕切部材の間の流体密性を高度に得ることができる、新規な構造の流体封入式防振装置を提供すること。【解決手段】流体封入式防振装置10であって、アウタ部材14の筒状部22の内周面に本体ゴム弾性体16の軸方向端部が固着されていると共に、本体ゴム弾性体16の軸方向端部がシールゴム部30を備えており、アウタ部材14の筒状部22の内周側に配設された仕切部材32が、軸方向端面の外周縁部に位置する押圧シール面56においてシールゴム部30の軸方向端面に押し付けられていると共に、押圧シール面56において軸方向外方へ突出する仕切部材32のシール突条54が、シールゴム部30の軸方向端面に対してより強く押し付けられて、シールゴム部30と仕切部材32の軸方向間が、流体密にシールされている。【選択図】図1
