PURPOSE:To improve vibration controlling and preventing effects by inter-connecting flanges at the engine and car body sides with a two-crest bellows filled with air and having rhe central deflecting section with thick wall and interposing an intermediate ring between the crests to behave reversely to the engine side. CONSTITUTION:A flange 12 at the engine side and a flange 14 at the car body side are interconnected with a two-crest rubber bellows 10 filled with pressurized air. A central deflecting section inside the crest of this bellows 10 is formed with a stopper section 19 having thick wall while an intermediate ring 11 is disposed between two crests. Mass of the intermediate ring 11 and spring constant of the bellows 10 are set such that the behavior of the intermediate ring has the opposite phase to that of the flange 12 at the engine side in the vibration preventing region of the engine. Thus, vibration controlling and preventing effects of an engine mount can be improved. |
