A synthetic resin-made thrust sliding bearingincludes a synthetic resin-made upper casing, a synthetic resin-made lower casing, and a synthetic resin-made thrust bearing pieceinterposed between the upper and lower casingsand. If it is assumed that the radial length of the thrust bearing pieceup to its outer peripheral surfaceis (r), and the thickness of an upper annular plate portionat its inner peripheral surface is (t), the upper casinghas on its upper surfacean annular flat surfacehaving a circular outer peripheral edge with R in a range of R=r&#xb1;t.

Synthetic resin-made thrust sliding bearing

In a synthetic resin-made thrust sliding bearing, a silicone grease whose base oil is a silicone oil, whose coefficient of kinematic viscosity at 25&#xb0; C. is not less than 100 cSt and not more than 500,000 cSt, and which contains a thickener so as to set its worked penetration to not less than 200 and not more than 400 is interposed at sliding interfaces between, on the one hand, an upper surface of a lower annular flat plate-shaped portion defining a bottom surface of a lower annular recess and a lower surface of an upper annular flat plate-shaped portion and, on the other hand, an upper surface and a lower surface of a thrust bearing piece which are respectively brought into sliding contact with the upper and the lower surface.
