PROBLEM TO BE SOLVED: To provide an underwater sliding member in which a surface being the sliding surface of a lubrication plug is not likely to be damaged during use.SOLUTION: An underwater sliding member includes a metallic substrate having a sliding surface and a lubrication plug. A plurality of holes or recesses open on the sliding surface are formed in the metallic substrate, and the lubrication plug composed of polyethylene is embedded in the holes or recesses. The molecular weight of polyethylene is preferably 200,000 or more. The lubrication plug may contain 20 vol.% or less of at least one resin selected from phenol, polyamide, polyimide, polyamide-imide, polytetrafluoroethylene, polyphenylene sulfide and polyoxybenzoyl, and further may contain 1 vol.% or less of a coloring agent.SELECTED DRAWING: Figure 1 |
