Turbine and turbocharger

Abstract

This turbine comprises: a turbine wheel; a first housing having a scroll flow path; a second housing that accommodates the turbine wheel between the first housing and the second housing, and forms a gas flow path from the scroll flow path toward the turbine wheel; a nozzle device including at least an annular first plate part and at least one fixed nozzle vane, the annular first plate part having a first flow path surface facing the gas flow path, and a first back surface that is a surface on the opposite side in the axial direction of the turbine wheel from the first flow path surface, and that forms a first space between the first housing and the second housing, the fixed nozzle vane being fixed to or supported on the first plate part and extending along the axial direction in the gas flow path; and a biasing member that is disposed in the first space and configured to bias at least one fixed nozzle vane toward the first housing via the first plate part.
