Claims

[Claims for Utility Model Registration] Between the first frame body 31 provided on the vibrating body and the second frame bodies 3 and 2 provided on the vibrated body, extending in one direction A; a first elastic member 33 having one end fixed to the first frame 31 and the other end fixed to the second frame 32;
Two fluid chambers 34.35 are defined that are filled with fluid and undergo substantially complementary changes in volume as the vibration rests, and the two fluid chambers 34.35 are communicated through a throttle passage 36 so that the fluid can flow. In the vibration isolator, the first
A first mounting portion 37 is formed on the frame 31 and extends substantially parallel to the first direction A toward the second frame 32 side, and a first mounting portion 37 is formed on the second frame 32 toward the first frame 31 side. A second mounting portion 38 extending substantially parallel to the first direction A is formed between the first mounting portion 37 and the second mounting portion 38, and is substantially orthogonal to the first direction A. It extends in the direction B, one end of the direction B is fixed to the first mounting part 37, and the other end is fixed to the second mounting part i.
A second elastic member 39 is fixed to the mounting portion 38, and the loss factor of the second elastic member 39 is set to a larger value than the loss factor of the first elastic member 33. - A vibration isolator characterized in that the dynamic magnification of the m member 33 is set to a smaller value than that of the second elastic member 39.・
