VIBRATION ISOLATING MATERIAL

摘要

PURPOSE:To prevent an elastic body from swelling by making a rubber-like elastic body forming a cylindrical casing and a highly viscous liquid member sealingly charged in its inside of materials different as much as possible in the value of their dissolution constant. CONSTITUTION:A cylindrical casing 2 formed of a rubber-like elastic body is provided between a pair of metal plates 1, and a hollow inside part surrounded by said casing 2 and said metal plates 1 is sealingly charged with a highly viscous liquid member 3 having a dissolution constant different as much as possible from that of the rubber-like elastic body. Thus contact between said liquid member 3 and said casing 2 can prevent the rubber-like elastic body forming said casing 2 from swelling.
