摘要
A cylinder block has a cast cylinder liner. A different level portion with a predetermined width is provided in a projected part formed along the lower end-face of the cylinder liner, in the centrifugal direction of the cylinder liner. In this case, the different level portion has a width corresponding to the dimensional tolerance range with respect to a finished inside diameter dimension position, and a outer circumference edge of the different level portion is provided in the outer circumference side farther than the finished inside diameter dimension position. Displacement of a hole is detected by checking the different level portion after machining the internal circumference of the cylinder liner.
