To provide a liquid sealed vibration control device capable of easily controlling deformation of a movable plate provided with slits on projections.SOLUTION: A plurality of annular projections (first projection 31a and second projection 31b) are respectively projected from a first surface 30a and a second surface 30b of a disc-like movable plate 30, and the projections are divided in a circumferential direction by slits 41-44. As the projections adjacent to each other in a radial direction are different in positions of the slits 41-44 in the circumferential direction, bending of the movable plate 30 at the slits 41-44 as starting points can be suppressed. Thus, the rigidity in the circumferential direction of the movable plate 30 can be unified even when the slits 41-44 are formed on the projections, so that deformation of the movable plate 30 can be easily controlled to suppress local deformation of a part of the movable plate 30 in the circumferential direction.SELECTED DRAWING: Figure 3
【課題】突起にスリットを設けた可動板の変形をコントロールし易くできる液封入式防振装置を提供すること。【解決手段】円板状の可動板30の第1面30a及び第2面30bからそれぞれ複数の環状の突起(第1突起31a及び第2突起31b)が突出し、その突起がスリット41~44によって周方向に分断される。径方向に隣り合う突起において、スリット41~44の位置が周方向に異なるので、可動板30がスリット41~44を起点に折れ曲がることを抑制できる。よって、突起にスリット41~44を設けた場合でも可動板30の周方向の剛性を均一化できるので、可動板30の周方向の一部が局所的に変形することを抑制するように可動板30の変形をコントロールし易くできる。【選択図】図3
