SLIDE BEARING

PROBLEM TO BE SOLVED: To facilitate connection to oil supply equipment or oil discharge processing equipment to shorten a term of work in execution and reduce a cost therefor.SOLUTION: This slide bearing 10 includes: a lower half bearing part 11 covering a rotating shaft 1 from below and having a lower slide surface 13 slidably supporting the rotating shaft; and an upper half bearing part 12 covering the rotating shaft from above, having an upper slide surface 14 slidably supporting the rotating shaft, and joined to the lower half bearing part. An oil supply passage 17 is formed in the lower half bearing part to supply lubricating oil into a clearance between an outer peripheral surface 2 of the rotating shaft, and the lower slide surface 13 and the upper slide surface 14, and an oil discharge passage 18 is formed in the lower half bearing part to discharge the lubricating oil from the clearance. A downstream portion of the oil supply passage 17 and an upstream portion of the oil discharge passage 18 are opposed to each other across the rotating shaft, and an upstream portion of the oil supply passage 17 is extended toward the upstream portion of the oil discharge passage 18, and a downstream portion of the oil discharge passage 18 is extended toward the downstream portion of the oil supply passage 17.
