Diffuser of an exhaust gas turbine

The exhaust gas turbine has a turbine wheel (30) with multiple rotor blades (31) and a guide device (70) for aligning the flow on the rotor blades of the turbine wheel. A flow channel is arranged downstream the rotor blades of the turbine wheel to guide the flow from the rotor blades to a gas outlet housing (20) and for a deflection from an axial direction into a radial direction. A turbine diffuser (82) is mechanically coupled on the gas outlet housing. The turbine diffuser and a housing portion (81) are connected with each other by rods (83) in the flow channel. An independent claim is also included for an exhaust gas turbocharger.
