PROBLEM TO BE SOLVED: To provide a half-split thrust bearing and a method of manufacturing the same, capable of effectively preventing fatigue separation and seizure of a lining layer even when local contact exists.SOLUTION: Undercut 15 is generated on a semicircular material 14 by punching out a bearing material 11 of a half-split bearing by pressing, thus a circular arc-shaped portion 13' continuously covering a surface 12A and a side face 12B of a back metal 12, is disposed on a radial edge portion of at least an inner peripheral side of a lining layer 13. Simultaneously, a thin portion 17 thinner than a thickness of a radial central portion of the back metal, is formed on the back metal, and a thickness of the thin portion 17 of the lining layer is thicker than a thickness of the radial central part. |
