ABSTRACT:
In a cylinder sleeve assembly comprising a plurality of cylinder sleeves whose adjacent cylindrical peripheral walls are coupled to each other, a plurality of sink mark inhibiting projections biting into the cylinder sleeve assembly during casting a cylinder block are provided in each of valley-like areas of an outer peripheral surface of the cylinder sleeve assembly which are located on opposite sides of a coupled portion of the adjacent peripheral walls. Thus, the adhesion between the cylinder barrel assembly and the cylinder sleeve assembly is enhanced. In addition, the adhesion is further enhanced by providing a predetermined inclination to each of the sink mark inhibiting projections.
