Abstract
A diffuser includes a connection section and a body section. The connection section extends from an outlet of turbine rotor blades. The body section is connected to an end of the connection section on a downstream side and has a larger flow passage sectional area than the connection section. The shape of the flow passage sectional surface of the connection section is formed into a circle at an outlet of the turbine rotor blades and is formed into an ellipse at an inlet of the body section. The shape of the flow passage sectional surface of the connection section is further formed to be gradually enlarged in a long-axis direction of the ellipse from the outlet of the turbine rotor blades toward the inlet of the body section.
