PROBLEM TO BE SOLVED: To provide a sliding member which is formed by combining a resin overlay and a soft metal overlay to improve foreign matter resistance while utilizing a low friction property of the resin overlay.SOLUTION: A sliding member has a soft layer 3 comprising a metallic material with a hardness of less than 40 HV provided in an under layer of a resin overlay layer 4 comprising a solid lubricant and resin. In the event of contamination by foreign matter, the soft layer 3 of the under layer of the resin overlay layer 4 is capable of plastic deformation and the resin overlay layer 4 is capable of partial deformation accompanying the plastic deformation due to the thickness T1 (μm) of the soft layer 3 and the thickness T2 (μm) of the resin overlay layer 4 having a relationship satisfying 0.2≤T1/T2≤7.0 and 3.0≤T1≤20.0. Consequently, foreign matter is desirably embedded and resistance to foreign matter can be improved. Further, a low friction property can be maintained by the resin overlay layer 4 even after contamination by foreign matter. |
