ABSTRACT:
An outer sleeve and an inner sleeve are connected to each other by an elastomeric member. Main liquid chambers and subsidiary liquid chambers, circumferentially connected to the main liquid chambers, are defined between the elastomeric member and the outer sleeve and communicate with each other through orifices. When a large load is input in directions X and X', the volume of the main liquid chambers are decreased, thereby causing the liquid forced out of the main liquid chambers to flow through the orifices, so that a damping force is produced by a resistance, due to a liquid, generated during flowing of the liquid. When a load in directions Z and Z' is input by a load in the directions X and X', the volume of the subsidiary liquid chambers adjoining the main liquid chambers is decreased, thereby causing the liquid, forced out of the subsidiary liquid chambers, to flow through the orifices, thus producing a damping force. Thus, it is possible to effectively damp the load applied in a main load-input direction and the load in a direction perpendicular to the main load-input direction.
