  • the coolant flow channel is not designed as an open recess portion as described in Japanese Patent Application Publication No. 11-49096 (JP-A-11-49096) but is formed inside a coupling member, and an exhaust gas cooling adapter that introduces a coolant into this coolant flow channel via an inflow port and discharges the coolant from an outflow port is formed.
