Laminated sliding member and sliding bearing using the laminated sliding member

A sliding bearing comprising:

• a lower shoe having a recessed portion which is open at one surface thereof;
• a rubber elastomer which is accommodated in the recessed portion of said lower shoe, and has an annular notched stepped portion at an outer peripheral edge of an upper surface thereof;
• an annular ring fitted and fixed in the notched stepped portion;
• an intermediate plate which is disposed on the upper surface of said rubber elastomer so as to be swingable and rotatable relative to said lower shoe, and has a recessed portion in an upper surface thereof;
• a laminated sliding member fitted and fixed in the recessed portion of said intermediate plate;
• and an upper shoe having fixed thereon a slide plate which is brought into slidable contact with a solid lubricant layer of the laminated sliding member,
• said laminated sliding member comprising:
• a base body having a plurality of recessed portions in one surface thereof;
• and the solid lubricant layer being adhered to at least the one surface of said base body,
• said solid lubricant layer extending into the plurality of recessed portions of said base body,
• wherein said base body has a laminate having the one surface and formed by superposing and mutually joining a plurality of polyester fiber woven fabrics impregnated with a resol-type phenolic resin containing a polytetrafluoroethylene resin,
• wherein said one surface of the laminate comprises an annular outer surface surrounded by an outer peripheral edge of the one surface of the laminate and by an imaginary line located in such a way as to be spaced apart a predetermined distance inwardly from the outer peripheral edge and similar in shape to the outer peripheral edge, and an inner surface surrounded by the imaginary line and located inwardly with respect to the annular outer surface,
• the plurality of recessed portions being open at the inner surface of the one surface of the laminate,
• each of the plurality of recessed portions being defined by a cylindrical wall surface in the laminate and a circular bottom wall surface in the laminate,
• wherein the one surface of the laminate, the cylindrical wall surfaces, and the circular bottom wall surfaces have fluff of the polyester fiber woven fabric, respectively,
• said solid lubricant layer being adhered to at least the one surface of the laminate in such a manner as to be formed integrally with the fluff in mixed form, and
• wherein said annular ring has a synthetic resin-made protective ring which is fitted in the annular notched stepped portion of said rubber elastomer and a metallic compression ring which is disposed on an upper surface of the protective ring and is fitted in the annular notched stepped portion of said rubber elastomer.
