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.
