Claims

[Scope of utility model registration request]

A radial turbine including a turbine rotor, a bearing housing that pivotally supports the turbine rotor, a scroll, and a variable nozzle blade provided in a flow path from the scroll to the turbine rotor, wherein the variable nozzle blade is rotatable. The nozzle blade support member is attached to the radial joint surface of the turbine rotor formed between at least one supporting nozzle blade support member and between the nozzle blade support member and the bearing housing. A variable nozzle radial turbine comprising at least one fastening member that prevents a turbine rotor from shifting in the circumferential direction.
