Abstract
A double orifice type liquid-in vibration isolating device including a partition portion fitted between a vibration isolating substrate combined through a body fitting and a first diaphragm made up of a partition main member forming a first orifice, a partition plate member forming a second sub-liquid chamber and a second orifice, and a partition support plate forming the first orifice. An inlet/outlet on the main liquid chamber side of both orifices is common to both orifices. The first orifice is diverged from a part of the second orifice having a liquid passing resistance smaller than that of the first orifice to provide two orifices compactly. Any variation or change of the property can easily be coped with by circumferential position adjustment of the component members of the partition portion.
