Abstract
Disclosed is a plain bearing having a back metal, a bearing alloy layer and an overlay layer, in which the bearing alloy layer and the overlay layer are formed on the inner surface of the metal in this order. The inner surface of the bearing alloy is provided with circumferential broad width recesses and narrow recesses in which the overlay material is filled. The fatigue resistance and were resistance are ensured by the zone of the narrow width recesses. The plain bearing exhibits high embeddability for a foreign substance by presence of the zone of the broad width recesses.
