Abstract
A turbine housing includes: a scroll section configured to internally define a spiral space; a cylindrical exhaust gas introduction section having an exhaust gas introduction port and configured to internally define a connection passage connecting the exhaust gas introduction port and the spiral space; a sheet metal inner scroll member disposed in the spiral space to form a first heat-shielding space between the inner scroll member and an inner surface of the scroll section and configured to internally define a spiral flow passage through which exhaust gas entering through the exhaust gas introduction port flows; and a sheet metal inlet member separate from the inner scroll member, disposed in the connection passage to form a second heat-shielding space between the inlet member and an inner surface of the exhaust gas introduction section, and configured to internally define a connection flow passage connecting the exhaust gas introduction port and the spiral flow passage. An upstream end portion of the inner scroll member and a downstream end portion of the inlet member overlap along an axial direction of the exhaust gas introduction section.
