ABSTRACT:
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 of the cylinder sleeve in the cylinder block has a notched conical surface as a notched inclined surface whose inside diameter gradually enlarges from the inner peripheral-surface of the cylinder bore toward the contact end surface with the cylinder head. An outer peripheral portion, on the cylinder side, of an endless ring-like gasket made of soft steel or stainless steel interposed between the cylinder block and the cylinder head has a taperingly conical surface as a taperingly inclined surface capable of being brought in close contact with the notched conical surface of the cylinder bore.
