ABSTRACT:
A dilatant fluid-sealed vibration-insulating device includes a connection member to be connected to one member, a holder to be connected to another member, an insulator provided between the connection member and the holder, the insulator being made of a rubber-like elastic material, a main chamber and an auxiliary chamber serially provided below the insulator. A partition plate separates the main chamber and the auxiliary chamber from each other. An orifice is formed in the partition plate to communicate the main chamber and the auxiliary chamber with each other. An air chamber is provided into which the air is introduced. A diaphragm separates the air chamber from the auxiliary chamber, and a dilatant fluid is sealed in the main chamber and the auxiliary chamber. When vibrations having very low frequency of about 5Hz and a relatively large amplitude are inputted to the vibration-insulating device, the dilatant fluid exhibits a relatively small viscosity increase insufficient to dampen the vibrations. The fluid comprises dilatant fluid of which frequency range exhibiting the dilatancy thereof is shifted toward a frequency higher than the very low frequency of about 5Hz.
