PROBLEM TO BE SOLVED: To retain an oil retaining function by grooves for a long period and preventing seizure by removing the adhered metal, when there is adhesion in a counter-shaft in a slide bearing formed with the grooves in a bearing alloy surface, storing the lubricating oil in the grooves, and reducing the friction coefficient with the counter-shaft. SOLUTION: The circumferentially extending grooves 12 and lands 13 flush with the bearing alloy surface are formed into the recessed/projecting state with their alternately aligned in the axial direction and in the circumferential direction in a part of the bearing alloy surface, to which high load is applied. This constitution allows the lands 13 to occupy a relatively large area so as to be hardly abraded and exhibit the oil retaining function of the grooves 12 for a long period. When circumferentially following the bearing alloy surface, the grooves 12 and the lands 13 are alternately emerged so that, when there is the adhesion in a crank pin, or the counter-shaft, the adhered metal can be removed by the lands 13 so as to prevent the development to the seizure.
