摘要： A positioning lug 13 is formed which curvedly expands outwardly along the circumference of a half-circular bearing body 11 from the external surface of the bearing body. The positioning lug 13 is provided so that both transition sections thereof are integrated at a circumferential ends 12 with the bearing body 11. Unlike a conventional sliding bearing half shell provided with a tongue-like positioning lug protruding from a proximal end line 14, with transition sections separated from the bearing body, the sliding bearing half shell according to the present invention does not undergo the failure of its positioning lug due to the fatigue of the proximal end line 14 caused by cyclic bending stress.
