VIBRATION ISOLATION DEVICE

摘要

To provide a vibration isolation device capable of preventing the sealing performance in liquid filling work from deteriorating and capable of simplifying maintenance of apparatuses in relation with the liquid filling work.;A liquid chamber is filled with liquid from a through hole 15 through a nozzle 41. A seal section is vulcanizingly formed in the periphery on one end side of the through hole 15. Because the seal section interferes with a nozzle 41 and is elastically deformed, the sealing performance in pouring in the liquid can be secured.;Also, because the seal section is arranged for every vibration isolation device 10, maintenance of a liquid filling device 40 can be simplified compared with a case the seal section is arranged in the liquid filling device 40.

主权项

1. A vibration isolation device, comprising:
a first attaching member connected to one of a vibration generating side and a vibration receiving side; a second attaching member connected to the other of the vibration generating side and the vibration receiving side; a vibration isolation base that connects the first attaching member and the second attaching member to each other in an elastically deformable manner and is formed of a rubber-like elastic material; a liquid chamber where liquid is filled, with the vibration isolation base being a part of a separation wall; a through hole that communicates with the liquid chamber, penetrates one of the first attaching member and the second attaching member, and pours in the liquid to the liquid chamber from one end side through a nozzle; and a seal member that is inserted from one end side of the through hole, seals the through hole, and prevents the liquid filled in the liquid chamber from leaking, wherein a seal section is provided which is disposed in the periphery on one end side of the through hole, is formed integrally with a rubber-like elastic material that is vulcanizingly adhered to the periphery on one end side of the through hole, interferes with an end surface or an outer peripheral surface of the nozzle, and is elastically deformed.
