PROBLEM TO BE SOLVED: To provide a turbine housing which effectively absorbs heat expansion and is easily manufactured at low costs.SOLUTION: A turbine housing 10 located in a turbocharger includes a bypass part P which exhausts exhaust air without causing the exhaust air to pass through a turbine wheel. The bypass part P comprises: a bypass pipeline 21 disposed on a flange 11 side at an intake side; and a bypass guide pipeline 22 disposed on a flange 13 side at an exhaust air outlet side. The bypass guide pipeline 22 is fixed to the flange 13 at the exhaust air outlet side by welding E and is slidably attached to the bypass pipeline 21.SELECTED DRAWING: Figure 2 |
