PROBLEM TO BE SOLVED: To provide a vibration-proofing device which suppresses torsion and improves durability as compared to the conventional technique by means of rubber volume of a rubber elastomer when a prizing force is inputted.SOLUTION: A vibration-proofing device includes: an inner cylinder 12; an outer cylinder 14 which is separated and arranged on the outer diameter side of the inner cylinder 12; a rubber elastomer 16 which is inserted between the inner cylinder 12 and the outer cylinder 14 and connects the inner cylinder 12 and the outer cylinder 14 elastically; and an intermediate plate 18 embedded in the rubber elastomer 16. A plurality of cutoff parts 36 which are located on both edge parts along the axial direction of the outer cylinder 14 and connect an inside rubber elastomer 16a and an outside rubber elastomer 16b are provided in the intermediate plate 18, and at least one of the plurality of cutoff parts 36 are arranged so as to be overlapped with an area S held by two parallel virtual surfaces T1, T2 which are brought into contact with the outer circumferential surface of the inner cylinder 12. |
