ABSTRACT OF THE DISCLOSURE An internal combustion engine has a crankcase coupled to a lower end of a cylinder block, the crankcase including an upper case integrally formed with the cylinder block and a lower case fixed to the upper case. The upper and lower cases have a plurality of journal support walls projecting from inner wall surfaces thereof. An oil pan is fixed to the lower open end of the lower case. A crankshaft is rotatably sandwiched by the journal suppo?? walls. A breather chamber is mounted on one side of the crankcase and defined by recesses on confronting surfaces of the upper and lower cases, the breather chamber having one end communicating with the crank chamber and an opposite end communicating with an air intake system. At least one balancer shaft is rotatably supported in a balancer chamber mounted on one side of the crankcase. The upper and lower cases define substantially semicylindrical recesses therein which jointly constitute bearings in which the crankshaft and the balancer shaft are rotatably supported. At least one of the upper and lower mating surfaces has an oil groove communicating with said recesses for being supplied with lubricating oil. The oil groove and the recesses are formed upon casting of the upper or lower case having the at least one of the upper and lower mating surfaces.
