PCT No. PCT/JP95/00468 Sec. 371 Date Nov. 16, 1995 Sec. 102(e) Date Nov. 16, 1995 PCT Filed Mar. 17, 1995 PCT Pub. No. WO95/25905 PCT Pub. Date Sep. 28, 1995Peaks 4b which extend circumferentially are formed around the inner peripheral surface of a bearing alloy layer 4 which forms a sliding bearing 2. When a total error resulting from manufacturing tolerances and an assembly error of a rotating shaft 3 and the sliding bearing 2 are denoted by W, the height of the peak by h, and an axial pitch of the peaks by p, the parameters W, h and p are chosen to satisfy the following requirements:2</=h</=10(1),1</=W</=8(2),h</=4W/3+14/3(3),50</=p</=600(4),andp</=-250h/3+3250/3(5)where h, p and W are measured in unit of mu m. Such selection of the parameters achieves an excellent abrasion resistance without providing an overlay layer around the inner peripheral surface of the bearing alloy layer 4.
