TO PROVIDE A SEALING STRUCTURE FOR A CYLINDER AND A CYLINDER HEAD, WHICH IS SIGNIFICANTLY EFFECTIVE FOR A RECIPROCATING TYPE INTERNAL COMBUSTION ENGINE IN WHICH A CYLINDER AND A CYLINDER HEAD ARE DETACHABLY CONNECTED WITH EACH OTHER THROUGH A GASKET. AN END PORTION, ON THE SIDE BEING IN CONTACT WITH THE CYLINDER HEAD, OF THE CYLINDER BORE (10) OF THE CYLINDER SLEEVE (8) IN THE CYLINDER BLOCK (3) HAS A NOTCHED CONICAL SURFACE (34) AS A NOTCHED INCLINED SURFACE WHOSE INSIDE DIAMETER GRADUALLY ENLARGES FROM THE INNER PERIPHERAL SURFACE OF THE CYLINDER BORE (10) TOWARD THE CONTACT END SURFACE (8A) WITH THE CYLINDER HEAD (4). ON THE OTHER HAND, AN OUTER PERIPHERAL PORTION, ON THE CYLINDER SIDE, OF AN ENDLESS RING-LIKE GASKET (35) MADE OF SOFT STEEL OR STAINLESS STEEL INTERPOSED BETWEEN THE CYLINDER BLOCK (3) AND THE CYLINDER HEAD (4) HAS A TAPERINGLY CONICAL SURFACE (36) AS A TAPERINGLY INCLINED SURFACE CAPABLE OF BEING BROUGHT IN CLOSE-CONTACT WITH THE NOTCHED CONICAL SURFACE (34) OF THE CYLINDER BORE (10).
