Claims

[Scope of utility model registration request]

In a variable displacement radial turbine in which a tongue-shaped member provided along a flow path of a turbine scroll is swingable in the radial direction of the turbine rotor to change the gas flow rate, the tongue-shaped member changes the gas flow rate. In the state where the tongue-shaped member is swung to the maximum position, the end edge of the tongue-shaped member along the flow path is brought into surface contact with the engagement surface formed on the side wall of the turbine scroll, and the tongue-shaped member is A variable displacement radial turbine characterized in that no gap is formed between a side surface and a side wall of the turbine scroll.
