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).

A synthetic resin-made thrust sliding bearing 1 includes a synthetic resin-made upper casing 100, a synthetic resin-made lower casing 200, and a synthetic resin-made thrust bearing piece 300 interposed between the upper and lower casings 100 and 200. If it is assumed that the radial length of the thrust bearing piece 300 up to its outer peripheral surface 303 is (r), and the thickness of an upper annular plate portion 102 at its inner peripheral surface is (t), the upper casing 100 has on its upper surface 108 an annular flat surface 109 having a circular outer peripheral edge with R in a range of R=rt.


A vibration isolation apparatus 1 includes: an annular laminated elastic body 6 in which elastic material layers formed of elastic plates 2 and rigid material layers formed of a plurality of annular thin-walled rigid steel plates 3 and a pair of annular thick-walled rigid steel plates 4 and 5 are alternately laminated; a cylindrical plug 9 formed of a vibration damping material and disposed densely in a cylindrical hollow portion 8 defined by at least an inner peripheral surface 7 of the laminated elastic body 6; upper and lower flange plates 12 and 11 respectively connected to the thick-walled rigid steel plates 4 and 5 by bolts 10; and a pair of annular shear keys 13 for each fixing each of the upper and lower flange plates 12 and 11 and a corresponding one of the thick-walled rigid steel plates 4 and 5 to each other at each of a lower surface and an upper surface of the cylindrical plug 9.
