Abstract

PURPOSE:To facilitate the fabrication and processing of a crankcase by a structure wherein lubricating oil passages are formed only within the wall of the split case belonging to the side formed smaller in size than the other side case in the system equipped with the crankcase split into left and right side cases. CONSTITUTION:The crankcase 11 of the engine unit 10 of motorcycle is split into the left and right side cases and the right side split case 16b is formed smaller in size than the left side split case 16a formed integral with a power transmission case 15. In this case, the lubricating oil in an oil pan 60 is sucked up by a pump 30 and led out to a oil passage 62 for feeding pressurized oil formed within the wall of the right side split case 16b, an oil cleaner 63, a main gallery 64 formed within the wall of the right side split case 16b, an oil supply passage 70, and branch passages 71, 73 and 75. Oil is supplied to the shaft bearing parts of the rotary shafts (a crankshaft 20, a balancer shaft 29 and a camshaft 32) at the side of the split case 16b through the interiors of the shafts.
