Abstract
A sliding bearing to be immersed in molten metal has low friction and long life. The bearing is provided with a solid particle trap portion for preventing solid particles in the molten metal from penetrating between sliding surfaces of the shaft and the bearing and removing the solid particles. Abrasive wear and an increase in friction, caused by biting of the solid particles into the sliding surfaces can be prevented. A continuous hot-dip plating apparatus employs the sliding bearing in the molten metal.
