Since it is made possible, it is possible to prevent the leakage of the working fluid between the tank body and the bottom member regardless of the compression of the elastic member by the bolt. As a result, even if the bottom surface of the tank body is distorted, there is no need to worry about leakage of the machining fluid, and the distortion of the machining fluid tank body (9) can be eliminated and the machining fluid does not leak as in the conventional case. Therefore, it is not necessary to tighten the bolt tightly and apply a large pressure force through the packing, so that the distortion of the machining liquid tank body (9) and the influence of the packing compression are transmitted to the table (6) and the surface plate (7), Work (8) fixed to the surface plate (7)
Since the accuracy of the mounting position is not obtained, the machining accuracy of the work (8) does not decrease.

に防止することができる。According to another invention, a processing liquid tank of a processing machine is provided with a tank main body having a bottom opening, a workpiece mounting table provided so as to project into the tank from the bottom opening, and a U-shaped section. In addition, a plurality of protrusions are formed on the surface facing the concave portion having the U-shaped cross section, and the concave portion having the U-shaped cross section is fitted over the entire circumference of the opening edge that forms the bottom opening of the tank body. Since the elastic member is provided on the entire circumference between the side surface of the workpiece mounting table and the opening edge and is compressed and sandwiched between the side surface and the opening edge, the bottom surface opening portion is elastic. No great force is required when the processing tank is fitted into the workpiece mounting table with the body member attached. As a result, the assembly can be facilitated and the leakage of the working fluid due to the plurality of protrusions can be reliably prevented.
