記載の液体タンク。[Scope of claim for utility model registration] (1) A tank body formed in a cylindrical shape with a bottom, an upper cover that covers the open end of the tank body and has a through hole formed therein, and a through hole in the upper cover. A liquid tank comprising a ring-shaped mounting flange located around the periphery and welded to the upper cover, and a lid member fastened to the mounting flange via a sealing member to close the through hole, The mounting flange includes a cylindrical outer wall portion including a cylindrical wall having an outer diameter larger than the through hole of the upper cover, and extends radially inward from the upper end of the cylindrical outer wall portion. It is formed of an annular flange wall portion to be fastened, and a cylindrical inner wall portion consisting of a cylindrical wall hanging from the inner diameter side of the annular flange portion, and a lower end of the outer peripheral side of the cylindrical outer wall portion is formed through the upper cover. A liquid tank characterized by having a structure in which the periphery of the hole is welded. (2) A utility model registration application in which bag nuts are attached to the annular flange wall of the mounting flange at multiple locations on the lower surface thereof to prevent liquid leakage when the lid member is tightened. Liquid tanks listed in scope item (1).
