    摘要： A lubricating oil feeding apparatus of an internal combustion engine (1) can adjust an amount of oil fed to each bearing and provides for a reduced number of parts for a shaft portion structure of a starter driven gear. In the engine, a balancer shaft (12) is synchronously rotated with a crankshaft (13). The crankshaft (13) and the balancer shaft (12) are rotatably supported on a split surface (3) of a crankcase (2) by plain bearings. Parallel oil passages (26,36) communicate with oil holes provided in the plain bearings (39a-d) for exclusively feeding lubricating oil to at least the crankshaft and the balancer shaft. The opening areas of the oil holes provided in the plain bearings of the balancer shaft are smaller than the oil holes (47) provided in the plain bearings of the crankshaft. An outer portion of a starter one-way clutch can also be integrally fitted on a rotor. A driven gear (44) of the starter (219) is connected to a starter drive gear (218) of a starter motor by intermediate gears. The diameter D b of a starter driven gear bearing portion of the crankshaft is the same as the diameter D a of a supporting portion of the crankshaft. A starter driven gear (44) (215) of the starter one-way clutch (211) is fitted to the starter driven gear (215) bearing portion of the crankshaft (13) by a slide bearing to be freely rotated relative to the starter driven gear (44) bearing portion. A lead groove is provided on the inner surface of the bearing for positively feeding oil to the receiving surface of the slide bearing.
