Abstract
Bearinghas base materialand coating layer. Base materialcontains crank shafton an inner circumferential surface side. The inner circumferential surface of base materialis coated with coating layer. The inner circumferential surface side of base materialis coated with a resin with a thickness t, the resin is dried, and thereafter surface treatment is carried out such that multiple grooves C are provided on the surface of the resin so as to intersect with the direction of crank shaft, whereby coating layeris formed. Peak portions B formed between adjacent grooves C come into contact with the outer circumferential surface of crank shaftto support crank shaft. With bearing, the thickness of peak portions B at the center in the direction of the crank shaftdiffers from the thickness of peak portions B at the end.
