Abstract
A bearing memberis provided with a coating layeron an inner circumferential surface of a shaft holeA into which a shaft bodyis to be fitted. The coating layeris composed of a metal base materialA and a heat conductive materialB that is dispersed in the base materialA and that has a thermal conductivity relatively higher than that of the base materialA. The heat conductive materialB has lengths Lb and Lc in directions B and C along a surface of the coating layer, longer than a length La in a thickness direction A of the coating layer, whereby thermal conductive characteristics in the directions B and C along the inner circumferential surface of the shaft holeA are enhanced. Thus, heat dissipation is improved, whereby temperature rise due to sliding contact with the shaft bodyis suppressed, and seizure resistance is improved.
