Also, even if parts are dropped during the assembling operation, the amount of liquid in the liquid tank is small, so it is easy to recover the parts. Also, the parts such as the main body parts, the partition and the diaphragm are transported outside the liquid tank. This enables early detection of trouble and quick response.

In addition, unlike the method of immersing the entire main body part in the liquid, foreign matters such as molding sand, rubber chips, burrs, etc. adhering to the outer periphery of the main body part do not enter the liquid.
In addition, air does not become bubbles and enter the liquid. In addition, the amount of liquid taken out of the liquid tank is small, and the liquid hardly adheres to the outer periphery, so that the cleaning operation after assembly becomes easy.

In particular, according to the liquid enclosing apparatus of the third aspect of the present invention, the liquid enclosing method of the present invention can be satisfactorily carried out, and each operation control such as positioning and assembling can be easily performed, and automation can be easily performed. . In particular, by operating the liquid tank elevating device with the main body fixing device holding the main body component in a fixed position, the control of the speed and position during assembly can be finely controlled, and the frequency of replacement of the seal member is reduced.

Further, in the case of the fifth aspect, the liquid can be supplied and discharged to the bottom portion of the liquid tank quickly and favorably by the raising and lowering action of the filling material, and the generation of bubbles due to the liquid supply can be prevented.
