。 Lubricating the crankshaft bearing, which consists of an oil hole provided in the journal of the crankshaft, and an oil groove in the semicircular arc-shaped bearing metal of the journal in which the lubricating oil that is supplied to the oil hole accumulates in the circumferential direction. In the oil passage, the upper bearing metal of the bearing metal mounted on the cylinder block is opened to the lubricating oil passage in the cylinder block and is spaced at a predetermined interval with a quarter arc dividing line of the upper bearing metal in between. A pair of separated communication holes is provided,
A first oil groove connecting the communication holes to each other is formed on the back surface of the Atsupa bearing metal, and a sliding surface of the Atsupa bearing metal is formed on the sliding surface of the Atsupa bearing metal except for a sliding surface extending over a range on the back side where the first oil groove is formed. A second oil groove is formed in the sliding surface of the lower bearing metal mounted on the crank cap among the bearing metals, with a quarter arc dividing line of the lower bearing metal interposed therebetween, and the second oil groove is interrupted at a predetermined interval. A lubricating oil passage of a crankshaft bearing, characterized by forming a third oil groove connected to the groove.
