Description of the Related Art Conventionally, a thermoplastic synthetic resin sliding member for the purpose of improving wear resistance and load resistance has been known as a multi-layered material in which a thermoplastic synthetic resin is adhered as a thin layer to a metal backing. Sliding member having a constitution, for example, a sliding member formed by forming a porous sintered metal layer on a steel plate and impregnating and depositing a synthetic resin on the porous sintered metal layer (Japanese Patent Publication No. 31-2452), metal. A metal mesh is filled and covered with a synthetic resin, which is joined to the inner peripheral surface of the housing to form a sliding member (Japanese Utility Model Publication No. 484411), and an adhesive layer is formed on a steel plate. A sliding member or the like that is attached is known.

く向上する。In such a multi-layer sliding member, even if it is a relatively soft synthetic resin, if it is applied as a thin layer on a backing metal such as steel, the resin itself will not bend or bend. Since no settling occurs, wear resistance and load resistance of the sliding member are improved as a result. Further, the frictional heat generated on the sliding surface is easily transmitted to the backing metal through the thin resin layer, and is radiated from the sliding member, so that the temperature rise can be suppressed low, and the above-described performance is further promoted. You. In addition, the resin is not likely to undergo expansion, contraction or aged deformation, so that the dimensional stability of the sliding member is significantly improved.
