Claims

[Scope of utility model registration request]

(1) An annular rubber elastic body through which a predetermined mounting shaft is inserted and installed so as to receive the main load in the axial direction; It includes an independent first pocket portion and a second pocket portion that are open and located on substantially the same circumference around the axis, and a part of the wall forming the second pocket portion is formed of a thin rubber portion. a pocket mechanism whose internal volume can be changed; and a pocket mechanism fixed to two ends of the rubber elastic body in the axial direction, and portions facing the first and second pockets are cut out as windows. a fixing plate that is placed on top of the fixing plate and fixed in a liquid-tight manner so as to seal the opening of each of the pockets liquid-tightly through the window; A circular arc portion of the plate along one circumference passing through each window portion is formed by press molding to curve toward the rubber elastic body side,
an inter-window curved portion in which a concave portion formed as a result of the curvature cooperates with the surface of the closing plate on the fixing plate side to constitute an orifice passage that allows the first pocket portion and the second pocket portion to communicate with each other; A cushion rubber device comprising: a predetermined incompressible fluid sealed in each of the first pocket portion and the second pocket portion.

(2) The pocket mechanism has a plurality of first pocket parts and a plurality of second pocket parts, and the first pocket parts and the second pocket parts are arranged alternately on substantially the same circumference. A cushion rubber device according to claim 1 of the utility model-registered claim, which is arranged in a utility model.

(3) The second pocket portion is formed on one side of the rubber thin film by bisecting a through hole that passes through the rubber elastic body in the axial direction with a rubber thin film that has slack in the middle. The cushion rubber device according to claim 1, wherein the thin rubber film is the thin rubber portion.
