PROBLEM TO BE SOLVED: To provide a thrust bearing with a low-priced stationary board which can join a bearing sliding surface forming board (polytetrafluoroethylene molding board or the like) with a base metal easily and which has high joining strength, capable of maintaining joining strength for a long time. SOLUTION: For stationary board for thrust bearing, a trapezoid protruding part 12a whose cross section in the thickness direction is of reversed trapezoid shape, is formed by processing. At the position facing the trapezoid protruding part 12a, a trapezoid recessed part 13a whose cross section is of trapezoid shape is formed. A sheet material 12A is joined integrally with a metal mold 13A by fitting both of them, and an anchoring effect is obtained by fitting the trapezoid protruding part 12a onto the trapezoid recessed part 13a. |
