Zusammenfassung:	A cylinder block has a different amount of oil supply for each journal, in which a plurality of bearing saddles are arranged at intervals and main bearings, which support main journals of a crank shaft, are respectively mounted to the plurality of bearing saddles. The bearing saddles comprise oil galleries formed in the cylinder block. Oil chambers are recessed from surfaces of the plurality of bearing saddles, to which an oil is supplied through the oil galleries, and communicate with end portions of the oil galleries to store the oil supplied from the oil galleries. The main bearings have oil holes through which the oil introduced into the oil chambers flow to the main journals. The amount of oil supplied to the main journals is determined according to an overlapped amount between the oil chambers and the oil holes.
