A sliding bearing includes a center portion and end portions on a bearing surface. Convexo-concave portions are respectively formed in the center portion and the end portions. The average height of the vertexes of convex portionsA in the center portion is set smaller than the average height of the vertexes of convex portionsB in the end portions. Average height Lof the convexo-concave portionA in the center portion and average height Lof the convexo-concave portionsB in the end portions are set to the same height. The center portion may be formed flat.

Sliding bearing

A sliding bearingis formed cylindrically of a pair of half bearingsand. A dust pocketformed of a recess part is formed in the inner peripheral edges of joining surfacesA andA of the half bearingsand, and foreign-substance discharge groovesand' are formed in a sliding surfacecontinuing from the dust pocket

A sliding bearingis formed into a cylindrical shape by placing abutting surfacesA andA of a pair of half-bearingsandso as to abut against each other. Two foreign substance discharging groovesand' inclined with respect to an axial direction of the sliding bearingare formed on a sliding surfaceadjacent to an inner circumferential edgeof the abutting surfacesA andA. When a lubricant is supplied to the sliding surface, a foreign substancemixed in the lubricant is trapped by foreign substance discharging groovesand&#x2032; and then discharged out of the sliding bearingfrom endsA andB (A&#x2032; andB&#x2032;) open to end facesand
