Claims

[Claims for Utility Model Registration] A mount body that supports a vibrating object on a foundation is provided with a chamber filled with liquid and an orifice portion that divides the chamber into a first chamber portion and a second chamber portion. , the above-mentioned first channel is connected to the orifice portion by a first diaphragm. The first chamber part and the second chamber part are prevented from communicating with each other.
a second primary orifice that is prevented from communicating with the first chamber portion and the second chamber portion by a second diaphragm; and a second primary orifice that prevents communication between the first chamber portion and the second chamber portion; and a secondary orifice that communicates with each other, and the movement amount characteristics of the first diaphragm and the second diaphragm are set to be different from each other. mount for.
