Abstract:
A vibration-proof device according to the present invention is provided with: a first cylindrical attaching member to be connected to one of a vibration generation part and a vibration reception part; a second attaching member to be connected to the other; an elastic body that connects the attaching members to each other; a partition member that partitions a liquid chamber in the first attaching member having a liquid sealed therein into a main liquid chamber in which the elastic body is a part of a wall surface and a sub-liquid chamber; and a movable member (40) that is housed in a storage chamber provided to the partition member so as to be deformable or displaceable in the axial direction of the first attaching member. An inclined projection (42) is formed in the outer peripheral edge of the movable member (40). The radial width (W) of the inclined projection at the root is smaller than the length (H) of the inclined projection from the root to the tip in the axial direction.
