PURPOSE:To restrain vibration in a three dimensional direction wherein vibration directions are compounded by providing a control means, exerting insertion resistance on internal fluid, between plural expansion vessels, connected in parallel to an article-to-be-vibrated and wherein fluid quantity is changed by displacement, and an accumulator absorbing the variation part of the internal fluid. CONSTITUTION:When a vibration direction has only a vertical direction component, the fitting plate 12 of respective expansion vessels 1 moves in parallel in a vertical direction by the movement of an article-to-be-vibrated B to expand and contract a bellows 11 by every equal quantity in the verbical direction respectively to insertedly conmmunicate internal fluid R, having the volume variation parts in the respective expansion vessels 1, with respective orifices 32 in a control means 3. At that time, an accumulator 2 displaces a bellow 21 by the access of the internal fluid R having the volume variation parts to absorb the variation part of the internal fluid R. Consequently, the internal fluid R receives resistance based on viscosity when insertedly communicated with the respective orifices 32 to act so as to restrain the vibration of the article-to-be-vibrated. |
