The surface of a lining member 3 is formed with a multiplicity of uneven surfaces 3a. The entire surface of the lining member 3 is coated by an intermediate layer 4 which comprises Ni. The surface of the intermediate layer 4 is additionally coated by an overlay layer 5 which comprises Sn alloy. The lining member 3 has a surface roughness t1, as a result of forming the uneven surfaces 3a, which is chosen to be in a range from 2 to 8 mu mRz, and a thickness t2 of the intermediate layer 4 is chosen to be in a range from 0.01 to 0.6 mu m. When a sliding bearing 1 is heated, the overlay layer 5 and the intermediate layer 4 chemically react with each other to produce Sn-Ni compound. As the overlay layer 5 becomes abraded, the Sn-Ni compound 6 will be exposed on the sliding contact surface. However, the described choice prevents the Sn-Ni compound from being exposed across the entire region of the sliding contact surface, thus improving the anti-seizure resistance of the sliding bearing 1. <IMAGE> |
