PURPOSE:To prevent unintentional oozing of the liquid having intruded between body metal-pieces likely to occur secularly by furnishing a sealing means to prevent leakage of the liquid having stagnated in the caulking overlapped portion of the metal pieces of an anti-vibration device, which absorbs vibration with the liquid flow resistance under vibration. CONSTITUTION:By caulking operation the tip of a supporting plate upper part 22A is pressed certainly to a step 12A except the coupling rubber 46A part, so that the liquid chamber sealing effect is high. Between caulked portion 12C and rising part 22A a gap is produced by buckling etc. of caulking metal-pieces for caulking the portion 12C to be caulked, and part of the liquid in a trough might intrude unintentionally. However, sealing rubber 46 is provided at the bore of this caulked portion 12C and the dia. enlarged portion 12B, so that eventually intruded liquid between the periphery of the rising part 22A and caulked portion 12C will cause the sealing rubber 46 to seal the outlet for the liquid to result in its encapsulation. Therefore, no secular leak of liquid will occur. |
