A sliding bearing and a crankshaft used for a crankshaft-connecting rod assembly are disclosed. Particularly, the invention concerns a sliding bearing for a crankshaft-connecting rod assembly, in which journal sections are each provided at each end of at least one crankshaft, one of said journal sections is rotatably supported so that said crankshaft is rotated about said one journal section, a connecting rod has one end rotatably coupled to said other journal section, and a lubricant is supplied form an oil port of each said journal section. The bearing surface of a cylindrical sliding bearing for supporting one of the journal sections with a predetermined clearance or the bearing surface of a cylindrical sliding bearing provided with a predetermined clearance between the other journal section and a connecting rod is formed with a recess, preferably a shallow recess, which corresponds in position to the oil port of each journal section, from which the lubricant is supplied or caused to flow, and extending in the circumferential direction of the sliding bearing. The invention further concerns a crankshaft, in which the outer periphery of at least one of the journal sections of the crankshaft is formed with a recess including the oil port extending in the circumferential direction of the journal section. |
