を特徴とする液封入防振装置の仕切板。 A ring in which a pair of liquid chambers consisting of chamber walls deformed by vibration input are partitioned by a partition plate, these liquid chambers are communicated through a throttle hole, and the partition plate is fixed along the inner circumferential surface of the liquid chamber. It consists of a fixed plate having a shape, and a movable plate disposed within the fixed plate and movable in a direction to alleviate the increase in internal pressure in the liquid chamber, and a stopper surface on the inner periphery of the fixed plate facing the outer periphery of the movable plate. In a liquid-filled vibration isolator that limits the movement of the movable plate to a certain range by forming a ring, the fixed plate is cut at one point in the circumferential direction to form a ring shape whose inner diameter is larger than the outer diameter of the movable plate. Then, the movable plate is inserted into the fixed plate, and the fixed plate is contracted and deformed until both the cut ends come into contact with each other, so that the stopper surface formed on the inner periphery of the fixed plate is opposed to the outer periphery of the movable plate. A partition plate for a liquid-filled vibration isolator, characterized in that a movable plate is held within a fixed plate.
