ABSTRACT:
A wet type sliding apparatus in which a multilayer sliding member is used in the presence of a lubricating oil, characterized in that the multilayer sliding member is composed of (1) a backing metal layer, (2) a porous, sintered layer provided thereon and (3) a surface layer consisting essentially of polyetheretherketone formed by impregnating and coating the porous, sintered layer with a sliding resin consisting essentially of polyetheretherketone. The above sliding member has a small friction coefficient and excellent wear resistance. In particular, the sliding noise can be more effectively inhibited by adjusting the face roughness of the surface layer of the sliding member to 2 .mu.m or less.
