PROBLEM TO BE SOLVED: To prevent dirt from adhering between a drain port and a drain port metal fitting.SOLUTION: A drain port metal fitting for being attached to a drain port is formed by a resin drain port metal fitting body 30, a stainless steel metal cover part 10, and a rubber packing 20. An outer edge of the metal cover part 10 is sharply folded back while securing the length of a folded part 14 longer than the radius of curvature of an outside surface. The edge of the folded part 14 is covered by a packing 20 from outside. Thereby, an overhang part 31 of the drain port metal fitting body 30 can be held so as to be sandwiched by a flange part 13 and the folded part 14 of the metal cover part 10 from the upper side and the lower side, and the radius of curvature of the folded edge can be sufficiently reduced. Therefore, a clearance between the metal cover part 10 and the drain port 101 can be sufficiently reduced, thus preventing dirt from adhering to the clearance. |
