PURPOSE:To reduce dynamic magnifying power in a high frequency vibration range inclusive of secondary vibration and improve a vibro-isolating characteristic in suchlike vibrations, by supporting a weight transversely inside a fluid chamber in a floating manner. CONSTITUTION:A bracket 15 is installed sideways from a cylindrical body 11 of a base member 10, while a rod 16 is set upright to an end top surface of the bracket 15, and a weight 50 is supported on this rod 16 by each of springs 51 and 52. When a high frequency vibration inclusive of secondary vibration is inputted into a setting member 20, the weight 50 moves up and down against these springs 51 and 52 but, due to its own inertia, almost comes to a standstill. In this case, if such force as acting on the base member 10 via share spring rubber 30 is made so as to balance with the force produced by vibrations in a relative position between the setting member 20 and the base member 10, dynamic magnifying power in a high frequency vibration range can be extremely reduced down, thus a vibro-isolating characteristic comes to being very excellent. |
