Abstract
There is provided a sliding member having excellent frictional wear properties not only under non-lubrication and under oil-lubrication but also under boundary lubrication. The present invention provides a multilayer sliding member including a porous metal layer formed on a sheet of back metal and a resin layer impregnated into and coated on the porous metal layer, wherein the above described resin layer contains 1 to 25 vol % of an oxybenzoyl polyester resin, 0.1 to 5 vol % of a hard particle material, 1 to 5 vol % of an inorganic compound, and polytetrafluoroethylene. Particularly, the addition of the inorganic compound enhances the oil-retention property under boundary lubrication, so that the frictional wear properties under boundary lubrication can be improved pronouncedly.
