Claims

[Scope of claim for utility model registration] Supports attached to the vehicle body and power units.
In a vibration isolation mount that has a support that is attached to the front side, and an elastic body and a partition plate that are interposed between these supports, both end surfaces of the elastic body are fixed to one of the supports and the partition plate, respectively. A gas chamber space is formed inside the elastic body, and a diaphragm and the other support are attached to the side of the partition plate opposite to the side to which the elastic body is fixed, so that liquid can be kept between the partition plate and the diaphragm. A gas-liquid mixing chamber is formed between the liquid chamber space and the diaphragm and the other support, and the liquid chamber space and the gas chamber space are connected through an orifice hole, and the diaphragm has six orifices. The chamber space for gas and the chamber space for liquid are each filled with gas and liquid that do not dissolve in each other, and the gas-liquid mixing chamber is filled with gas within the operating temperature range of the vibration isolation mount. A vibration-proof mount characterized by enclosing a gas-liquid mixture in a liquid state.
