Claims

[Scope of utility model registration request]

A cylindrical insulator rubber having a void inside, a pair of flanges connected to both ends of the insulator rubber, one of which has an opening connected to the void of the insulator rubber, and a pair of flanges attached to one of the flanges. , disposed within the void,
a partition plate that forms a lower chamber in the gap and is provided with an orifice; and an upper chamber that has a peripheral edge fixed to one of the flanges by a presser plate and that communicates with the lower chamber through the orifice of the partition plate. and a diaphragm formed between a diaphragm and the above-mentioned partition plate, and in which at least part of the lower chamber and the upper chamber are filled with fluid, the above-mentioned partition plate is protruded into the gap. The diaphragm is extended to form a lower chamber, and the center portion of the diaphragm is curved downward from its mounting surface to extend toward the upper chamber, and the retaining plate is arranged so that only its peripheral portion is connected to the diaphragm. the center so that it touches
The diaphragm is formed by extending or being cut out on the side opposite to the partition plate, so that when the volume of the upper chamber increases, the diaphragm can extend to the side opposite to the partition plate. Characteristic anti-vibration support device.
