を形成したことを特徴とする防振体。Two mutually independent frames and disposed between these frames,
and an elastic member fixed to both of the frames, a hollow fluid chamber formed within the elastic member and filled with fluid, and a sub-chamber separated from the fluid chamber via a partition plate; an orifice formed in a partition plate to communicate between the fluid chamber and the sub-chamber, one of the two frames facing the vibrating body;
The other is attached to the vibrated body side, and the vibration transmitted from the vibrating body side to the vibrated body side is suppressed by the vibration absorption function of the elastic member itself and the damper action when the fluid passes through the orifice. A vibration isolator characterized in that a guide portion whose diameter increases outward is formed at the opening end of the orifice.
