ABSTRACT:
There are provided a plain bearing which is excellent in oil retaining property and wear-resistant property. The plain bearing has a number of fine grooves which are parallely formed with one another and extending in the circumferential direction on the inner surface of the bearing, the fine grooves comprising deep grooves and shallow grooves. When this bearing is used as a plain bearing, a large amount of lubricating oil can be retained in the deep grooves and the shallow grooves so that a plain bearing which is excellent in anti-seizure property and wear-resistant property can be obtained. Further, even if the shallow grooves will have been worn out by wear and tear during use of extended period of time, the anti-seizure property and the wear-resistant property can be stably maintained by the lubricating oil retained in the deep grooves.
