Abstract
A sliding bearing comprises a shaft hole for rotatably supporting a shaft that is inserted thereinto, an inner circumferential surface on which the shaft slides, and plural linearly oblique grooves. The grooves extend in a direction crossing a circumferential direction of the sliding bearing and are formed on the inner circumferential surface at intervals, and the grooves are provided with a lubricant. The oblique grooves have an oblique angle in a range of 10° to 60° with respect to a direction perpendicular to the circumferential direction and have a width B in a range of 0.5 to 5 mm in the circumferential direction. The adjacent grooves have a land with a surface as a sliding surface therebetween, and the sliding surface has a width A in a range of 1 to 7 mm in the circumferential direction. A ratio A/B of the width A of the sliding surface of the land to the width B of the groove is in a range of 0.5 to 5.0.
