Abstract
A sealing structure in an exhaust system of an internal combustion engine includes a gasket which is clamped between a cylinder head and a flange fastened to the cylinder head and which has a sealing portion surrounding an exhaust port opening into a side of the cylinder head, and an exhaust pipe which is curved and coupled to the flange and which is in communication with the exhaust port. In this sealing structure, the sealing portion of the gasket is formed into an endless shape to surround said exhaust port, such that the distance between the sealing portion and a peripheral edge of the exhaust port, at least at a location substantially corresponding to a projected position of the exhaust pipe on the flange, is larger than the distance at other locations. Thus, it is possible to prevent or minimize the deterioration of the sealing portion of the gasket due to heat, while avoiding an increase in size of the section associated with the exhaust system.
