<p>This invention relates to a liquid sealed rubber mount capable of displaying an excellent vibration isolating effect in intermediate and high frequency ranges, having a vibration isolating effect with no resonation occurring with respect to even the impact vibration of a wide frequency band, capable of obtaining a large attenuation force when the amplitude of vibration is large, and capable of preventing the occurrence of lateral vibration. Accordingly, a case (11) and a guide shaft (14) are joined to each other with cylindrical mount rubber (17), and a high attenuation liquid (21) is sealed in a liquid sealing chamber (20) fixed to a lower end of the case (11), a damper plate (23) being held on a lower end of the guide shaft (14). An elastic member (24) which is deformed finely by a due to the resistance of the high attenuation liquid (21) when vertical vibration occurs is fixed to the upper and lower surfaces of the damper plate (23). When intermediate and high frequency vibration the amplitude of which is not more than +/-a occurs, the elastic member (24) is deformed and not attenuated, and a vibration isolating action occurs owing to the mount rubber (17). When low frequency vibration the amplitude of which is in excess of +/-a occurs, the damper plate (23) and elastic member (24) are moved unitarily, and an attenuation force occurs. <IMAGE></p> |
