Abstract
The invention relates to an exhaust gas cooling adapter that is arranged between an exhaust port that is open to a cylinder head of an internal combustion engine and an exhaust manifold, and that includes an exhaust gas flow path through which exhaust gas flows from the exhaust port to the exhaust manifold; and a coolant flow path that is formed inside of an adapter wall surrounding this exhaust gas flow path, and that cools the exhaust gas that flows through the exhaust gas flow path. There is a curved portion in the exhaust gas flow path. Also, a peel inhibiting portion is formed on an inner peripheral surface of the exhaust gas flow path in a region farther toward an inside of the curve than an exhaust gas flow path center line of this curved portion.
