Zusammenfassung:	PROBLEM TO BE SOLVED: To enhance an adhesive effect of mutual parts weck to balance accuracy by minimum fastening force by putting a rib in a grounding surface in metallic packing such as sealing packing for a drain cock of an oil pan. SOLUTION: Since a product on which mass production work is performed is made in a standard tolerance, there is a tendency of causing an inclination on a grounding surface of mutual parts. Then, for example, when it is performed on metallic packing such as sealing packing for a drain cock of an oil pan, a rib is formed on its grounding surface. Therefore, an adhesive effect of the murual parts inferior to balance accuracy can be enhanced by minimum fastening force. In this case, when coloring is performed on a reverse recess part bottom surface, whether or not it is a reused part can be easily judged by its coloring separation.
