<p>PURPOSE:To improve vibration transmission characteristic of a mount device by disposing an orifice in series to an elastically deformed intermediate chamber provided on a partition plate and mounting a valve on the partition plate, which is adapted to move for high frequency and is restrained to move for low frequency. CONSTITUTION:A partition plate 5 disposed on a mount device is provided with the first and second orifices 13, 14 having resonance point in low-frequency area, which are respectively disposed in series to the first valve mechanism 9 and the second valve mechanism 12, which are movable for high-frequency slight vibration and restrained to move for low-frequency large-amplitude vibration. Since the resonance frequency of the first valve mechanism is 60-170Hz, that of the second valve mechanism is 250-300Hz and that of the first orifice is 6-15Hz, vibration can be absorbed effectively.</p> |
