Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent an occurrence of cavitation by preventing abrupt opening and closing of an oil passage receiving a lubricating oil supplied from an oil groove formed on a shaft side in regard to a slide bearing having an oil groove formed with ends in an inner circumference along a circumferential direction. SOLUTION: An extension groove 13 extending in a circumferential direction from both ends of an oil groove 12 is formed and a width of this extension groove 13 is set smaller than a bore of an inlet 16a of an oil passage. By this, the inlet 16a of the oil passage formed on a shaft transits to a fully-opened state by the oil groove 12 via a half-opened state by the extension groove 13 during opening for preventing abrupt opening of the inlet 16a. Thereby, abrupt changes of a flow of a lubricating oil is prevented and an occurrence of cavitation is effectively prevented.
