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.

A more durable rotation transmitting member for a coupling directly connected to shafts has: drive-side rotation transmitting cushion to which an input shaft is directly connected; and a hub to which an output shaft is directly connected. Two parallel flat surfaces are formed on the outer periphery of the front end of the input shaft, and a shaft hole receives the front end of the input shaft and is formed in the rotation transmitting cushion. Surfaces of the inner wall of the shaft hole protrude toward the axis (O) to face input shaft front end flat surfaces. Each protruding surface comprises two flat sloped surfaces extending in the direction of the axis (O). When the input shaft starts to rotate, each front end flat of the front end comes into surface contact with one of the protruding surface sloped surfaces which faces the flat surface.

A sliding bearingincludes a cylindrical bearing body; slits provided in the bearing body; straight grooves provided on an inner side of the bearing body in such a manner as to extend in an axial direction A and respectively disposed between adjacent ones of the slits which are adjacent in a direction B about an axis; a sliding surface which is provided on the inner side of the bearing body and partially severed in the direction B about the axis by the slits to and the straight grooves; a fitting groove provided in an outer surface of the bearing body; and an elastic ring which is fitted in the fitting groove. Each of the straight grooves are closed on an end face side and is open on an end face side.
