Abstract
A hydraulic antivibration device arrangement capable of achieving a downsizing and weight reduction, and a reduction of booming noise by suppressing a reaction force to impingement upon stopper action is provided. By disposing a protuberant rubber portionat an upper end of a main body member, its spacing distance from a roll center can be lengthened, the reaction force to impingement can be diminished, and input load to the main body membercan be diminished. Consequently, reduction of rigidity and strength required for respective components as well as enhancement of durability is possible, which permits to make the components thin-walled thereby making a hydraulic antivibration device arrangementlightweight as a whole. Diminishing of such reaction force upon stopper action also enables vibrations input through a car body side bracketto the body frame to be suppressed, thereby reducing the generation of booming noise.
