の問題も避けることができない。(Problems to be Solved by the Invention) In the method for manufacturing the liquid-filled mount described above, the process of inserting the partition plate 6 and the diaphragm 4 into the case 3, the process of extrapolating the case cover 9 to the case 3, and the press operation are performed. The process of joining the case 3 and the case cover 9 is done in the liquid stored in the hydraulic fluid tank, and all parts are assembled by hand, making it almost impossible to automate the process and making it difficult to assemble. Not only does it take a long time, but it can also lead to errors in the combination of parts.
There is a high risk that air bubbles may remain in the filled liquid and cause functional deterioration, and it is also troublesome to clean and dry the hydraulic fluid that adheres to the outside surface, and to wipe off the liquid that scatters around the liquid tank. Accordingly, problems such as difficulty in work due to immersion of hands in cold liquid during winter cannot be avoided.
