LIQUID-SEALED VIBRATION ISOLATION DEVICE AND VIBRATION ISOLATION UNIT

摘要

PROBLEM TO BE SOLVED: To provide a liquid-sealed vibration isolation device and a vibration isolation unit capable of controlling regulation of the position of arrangement of a partitioning member by a hole for evacuation and for injection even when the hole for evacuation and for injection is formed for filling the inside of a liquid sealing chamber with the liquid by reducing the pressure in the liquid sealing chamber.;SOLUTION: A diaphragm 14 is subjected to vulcanization-adhesion to the inner circumference of an annular fitting member 44 formed in the annular shape when viewed in the axial direction, and a hole 44c for evacuation and injection is arranged in the annular fitting member 44. Thus, the position of arrangement of a partitioning member 15 is not limited by the hole 44c for evacuation and injection compared with the conventional product in which the hole for evacuation and injection is formed in the side face of, for example, an outer cylindrical member, and the partitioning member 15 can be arranged at an optional position.;COPYRIGHT: (C)2013,JPO&INPIT
