Abstract: PROBLEM TO BE SOLVED: To inexpensively manufacture a plain bearing having an oil groove on its inside-diameter face with high dimensional accuracy. SOLUTION: This method of manufacturing a plain bearing applies a press working method including a drawing process capable of molding a cylindrical portion of a metal sheet with a comparatively high yield rate and high accuracy, the press working includes a shearing process for shearing and thinning the cylindrical portion between a punch 12 and a die 11 and controlling dimensions such as an inside-diameter, a thickness or the like with high accuracy, a plurality of projections 12a are formed on the outer-diameter face of the cylindrical punch 12 used in the shearing process, the projections 12a are transferred to the inside-diameter face of a cup-shaped molding 4 as a groove, and the oil groove is formed on the an inside-diameter face of the plain bearing in a state of leaving the groove transferred to the inside-diameter face of the cup-shaped molding 4 on the cylindrical body which is cut in round slices, and thus the plain bearing having the oil groove on its inside-diameter face can be inexpensively manufactured with high dimensional accuracy without implementing other processes such as a grinding process and a coining process.
