SEALING STRUCTURE OF MOLDED BODY

摘要

PROBLEM TO BE SOLVED: To provide a sealing structure of a molded body capable of providing highly reliable sealability as the mating face of the molded body. SOLUTION: A metal body 5 and a metal body 6 higher in hardness than a cylinder block 1 and a cylinder head 2 body are cast to the mating faces of the cylinder block 1 and the cylinder head 2 of an engine to form them integrally with each other. An annular projected line 5a projected along a cylinder bore is formed on the metal body 5 to secure high surface pressure at the mating faces of the cylinder block 1 and the cylinder head 2 so as to provide the highly reliable sealability.
