ウント装置。[Scope of claim for utility model registration] An inner cylindrical metal fitting and an outer cylindrical metal fitting arranged concentrically or eccentrically at a predetermined distance in the radial direction, and interposed between the inner cylindrical metal fitting and the outer cylindrical metal fitting. between the inner cylindrical metal fitting and the outer cylindrical metal fitting,
two or more main liquid chambers provided on one side in the radial direction to which the main vibration is input, each of which is filled with a predetermined incompressible fluid and which causes an internal pressure change when the vibration is input; a movable member that is housed and arranged in the liquid chamber so as to be freely movable a predetermined distance in the vibration input direction, and forms a vibration acting part with a predetermined gap between it and the inner surface of the main liquid chamber; A communication hole provided in a partition wall partitioning the main liquid chambers and communicating the main liquid chambers with each other, and between the inner cylindrical metal fitting and the outer cylindrical metal fitting,
a sub-liquid chamber provided independently at a position spaced apart in the circumferential direction from the main liquid chamber, and in which a relative internal pressure fluctuation is generated between the main liquid chamber and the main liquid chamber when vibration is input; A fluid-filled cylindrical type characterized by having an orifice passage that communicates one of the liquid chambers with the sub-liquid chamber and allows fluid to flow between the two liquid chambers. Mounting device.
