Claims

[Scope of utility model registration request]

A chamber airtightly provided in the main body, which has a vibration-proof base made of a rubber elastic body, is divided into two chambers by a partition, and a liquid is sealed in both chambers. The partition plate is formed by a fixed side partition plate provided on each flat plate part and a movable side stopper member having plate bodies on both sides of the flat plate part and capable of closing each of the through holes alternately from one side. , a liquid damping vibration isolation mount in which the two chambers are communicated through an orifice and each through hole, wherein the movable stopper member is provided with a valve portion formed by a cut at a location corresponding to the through hole; The liquid damping type valve functions as a safety valve in which in a steady state, the valve only has a cut and is closed, but in an abnormal state where a large liquid pressure difference occurs between the two chambers, the valve changes to open by deforming along the cut. Shake mount.
