Abstract
In order to provide a plain bearing excellent in the anti-seizure property, a bearing metal layer is provided with a plurality of recesses different in depth on the inner surface thereof so as to form an uneven textured portion thereon, the recesses being filled with a soft overlay layer. At the beginning of the use, the overlay layer develops the conformability. When the wear proceeds to the wear level I so that the shallow recesses disappear, an intermediate layer or the bearing metal layer forming protrusions is exposed and form a condition in which the overlay is mixed. Furthermore, when the wear proceeds to the wear level II, the shallow recesses disappear while the deep recesses remain, so that the condition hardly to cause the seizure is maintained.
