Provided is a thrust sliding bearing which, while allowing a shaft member to smoothly rotate, can support for a long period of time a thrust load acting on the shaft member. A thrust sliding bearing comprises: an upper case (2) mounted to an upper support for mounting a strut-type suspension to a vehicle body; a lower case (3) mounted to an upper spring seat for supporting the upper end of the coil spring of the strut-type suspension, the lower case (3) being combined with the upper case (2) to form an annular space (5); and an annular center plate (4) disposed in the annular space (5) and enables the relative rotation between the upper case (2) and the lower case (3). The annular space (5) is filled with lubricating grease. The center plate (4) comprises: a bearing surface (42) in slidable contact with the surface (27) to be supported of the upper case (2); and annular protrusions (47, 48) provided at the inner peripheral edge and the outer peripheral edge of the bearing surface (42) so as to extend in the circumferential direction of the center plate (4).

A sliding bearing formed from a member containing resin, wherein the effect of thermal expansion of the resin is reduced. A bearing surface (10) that slidably holds the outer peripheral surface of a rotating body is formed on the inner peripheral surface (11) of the sliding bearing (1), which is cylindrical, and the sliding bearing (1) is a cylindrical multi-layer sliding member which is manufactured by roll-molding a base material that has been impregnated with a base resin. A plurality of through-holes (13) that pass between the inner peripheral surface (11) and the outer peripheral surface (12) are formed at suitable intervals in the bearing surface (10) and within a range that enables the sliding bearing (1) to maintain a required load-bearing strength. A solid lubricant (14) that has higher thermal conductivity than air and a lower thermal expansion coefficient than the base resin is embedded in the through-holes (13) in accordance with a required sliding performance and use conditions (such as the continuous use time in the atmosphere). A substance comprising graphite alone, a substance made of a resin that contains graphite, or the like is used as this type of solid lubricant (14).
