Abstract

PURPOSE:To facilitate the positioning of oil passages by dividing a crank case to right and left, and mutually communicating each oil passage respectively formed in a pump cover installed in one divided case and in the other divided case. CONSTITUTION:Crank cases 1, 2 are divided to right and left in a pair, and are respectively casted with the light alloy. At this stage, an oil pump 3 is installed in the outside of one crank case 1. A rotary shaft 4 of the oil pump 3 is connected to a crank shaft not showed in the figure through a gear 7. Further, an oil passage 10 is integrally formed in a pump cover 9 covering the inside of the oil pump 3. On the other hand, an oil passage 11 is integrally casted in the other crank case 12, projecting to the inside. Respective oil passages 10, 11 are communicated with each other by mutually engaging each crank shaft 1, 2 on right and left in a pair.
