PROBLEM TO BE SOLVED: To provide a vibration isolation device capable of preventing reduction of sealability in liquid charging work and capable of simplifying maintenance of a device concerned with the liquid charging work.SOLUTION: A mounting plate 14 and a base part 11a are coupled to each other by a vibration isolation base body 13 so as to be elastically deformed and a liquid chamber utilizing the vibration isolation base body 13 as a part of a diaphragm is formed. A liquid is charged from a through-hole 15 to the liquid chamber through a nozzle 41. A lip part 16d is formed on the one-end side periphery of the through-hole 15 by vulcanization molding integrally with a diaphragm 16. Since the lip part 16d is elastically deformed while interfering with an end face of a nozzle, sealability when a liquid is injected can be secured. Further, since the lip part 16d is formed in each vibration isolation device 10, repeated use of the lip part 16d can be prevented. Consequently, reduction of sealability in liquid charging work can be prevented and maintenance of a liquid charging device 40 can be simplified. |
