Claims

[Scope of utility model registration request]

A mount body that supports a vibrating object on a foundation is provided with a chamber filled with liquid and an orifice section that divides the chamber into a first chamber section and a second chamber section. 1 on the chamber side
A next orifice and a secondary orifice are provided, and a second orifice is also provided on the second chamber portion side of the orifice portion.
A downstream orifice section and a secondary orifice are provided, the primary orifice and the secondary orifice on the first chamber section side and the primary orifice and the secondary orifice on the second chamber section side. A diaphragm is interposed between the first chamber portion and the second chamber portion, and even when the diaphragm is displaced and blocks the primary orifice, the secondary side of the first chamber portion is interposed between the first chamber portion and the second chamber portion. A mount for supporting a vibrating object, characterized in that a communication hole is formed in the diaphragm to communicate the orifice with the secondary orifice on the side of the second chamber portion.
