PURPOSE:To achieve high damping characteristic under low frequency region and low dynamic spring constant under high frequency region in a mount encapsulated with fluid containing a rubber body while formed with two fluid chambers by communicating between fluid chambers through a communication path forming member laminated with plural plates. CONSTITUTION:An annular rubber sleeve 8 is fitted between inner tube metal 4 and outer tube metal 6 arranged coaxially and vulcanization adhered to each metal 4, 6 while first and second arched fluid chambers 10, 12 are formed symmetrically in said rubber sleeve 8. Here, a plate 14 of flat bottomed tube is secured to the end face at the opening side of fluid chambers 10, 12. While annular sheet plate 18, intermediate plate 20, sheet plate 22 and choking plate 24 are lapped sequentially at the inside of tubular section of said plate 14 and integrated liquid-tightly. Thereafter, both chambers 10, 12 are communicated through annular communication path 26 defined between said plates 18, 20. |
