Claims

[Claims for Utility Model Registration] (1) The center member 1 fixed to either the machine base side or the supported body side and the case member 4 fixed to the other side are connected by a spring member 7 made of a rubber-like elastic material. An airtight chamber 10 is formed between the spring member 7 and a diaphragm 8 arranged inside the case member 4, and the airtight chamber 10 is partitioned into two chambers by an orifice member 31. In a liquid-filled mount in which a working fluid is sealed in a sealed chamber 10, some parts constituting the orifice member 31 are connected to an external drive source to be rotatable and swingable. A liquid-filled mount characterized by variable orifice characteristics. (2) Utility model registration claim 1, characterized in that a plurality of channels 43, 46 having different orifice characteristics are formed in the orifice member 31, and opening and closing of the channels 43, 46 are switched. liquid-filled mount. (3) The liquid-filled mount according to claim 1, wherein the cross-sectional area of the opening of one channel 55 formed in the orifice member 31 is increased or decreased.
