Abstract:
A turbine T includes an impeller 2 and a housing 5. The housing 5 includes a housing outlet, a first scroll flow path 51 that is located radially outside the impeller 2 and guides fluid to the impeller 2, and a second scroll flow path 52 that is located radially outside the impeller 2 and closer to a housing outlet than the first scroll flow path 51 in the central axis direction, and guides fluid to the impeller 2. In a cross section parallel to and including the central axis, the second scroll flow path 52 is inclined with respect to the radial direction so as to recede from the housing outlet in the central axis direction as the impeller 2 is approached in the radial direction. In the above cross section, a region including an outlet 54 of the second scroll flow path 52 includes a first portion P1 having a linear shape parallel to the radial direction, and an R-shaped second portion P2 that is continuously formed radially outward from the first portion P1.
