Abstract
There is provided a sliding member formed by combining a resin overlay and a soft metal overlay. The sliding member has a soft layer comprising a metallic material with a hardness of less than 40 HV provided under a resin overlay layer comprising a solid lubricant and resin. In the event of contamination by a foreign matter, the soft layer under the resin overlay layer is capable of plastic deformation and the resin overlay layer is capable of partial deformation accompanying the plastic deformation due to the hardness (T) (μm) of the soft layer and the hardness (T) (μm) of the resin overlay layer being such that 0.2≤T/T≤7.0 and 3.0≤T≤20.0. Consequently, a foreign matter is desirably embedded and resistance to a foreign matter can be improved. Low friction is maintained by the resin overlay layer even after contamination by a foreign matter.
