PROBLEM TO BE SOLVED: To provide a turbine housing having a structure to be easily mounted and hardly causing degradation of sealing performance of a water passage.SOLUTION: A gas passage 35 connected to an exhaust passage 13, and a water passage 36 connected to a water jacket 15 are formed inside of a turbine housing 31. The water passage 36 and the gas passage 35 are arranged side by side on a connecting portion 51 at an exhaust gas introduction side of the turbine housing 31, and a connection face 52 to which the water passage 36 is opened and a connection face 53 to which the gas passage 35 is opened are not continued to each other. The turbine housing 31 is mounted on the cylinder head 14 in a state that an O ring 56 for suppressing leakage of cooling water is held between the connection face 52 and a cylinder head 14, and a seal member 55 for suppressing leakage of an exhaust gas is held between the connection face 53 and the cylinder head 14. |
