Abstract
A crankcase includes first and second case halves which are coupled to each other at a parting plane extending to obliquely intersect the axis of first and second bearing portions. A cylinder barrel and the first bearing portion are formed by molding integrally on the first case half to form an engine block. The second bearing portion is formed by molding integrally on the second case half and a side cover is coupled to an outer side surface of the engine block to define a valve operating chamber for accommodation of a valve operating mechanism. Thus, the distance between the first and second bearing portions for supporting opposite ends of a crankshaft can be reduced without being interfered by the valve operating mechanism, thereby enhancing the durability of the crankshaft. The valve operating mechanism can be assembled after coupling of the first and second case halves forming the crankcase, whereby the assemblability of the valve operating mechanism can be improved.
