<p>PROBLEM TO BE SOLVED: To provide a turbine housing of a supercharger capable of automatically adjusting a flow rate of exhaust gas flowing in a scroll part even if a waist gate valve is not used, and capable of reducing the size and weight. SOLUTION: This turbine housing 11 has the scroll part, a cover part 13, and flange parts 16 and 17. The scroll part is dividedly formed as a first scroll part and a second scroll part 12b. The second scroll part 12b has half-split parts 12c and 12d dividedly formed in a half-split shape. A slide part 20 by combining the mutual half-split parts 12c and 12d can open and close in response to the flow rate of the exhaust gas flowing in the scroll part. The flow rate of the exhaust gas flowing in the scroll part is automatically adjusted by switching an opening state and a closing state in this slide part 20.</p> |
