The variable-capacity turbine according to this invention is provided with a nozzle adjustment mechanism, having a nozzle drive components, a lever and nozzle vane, would all be housed at the inner side of the scroll in the turbine casing. This would reduce the axial length of the turbine and make it more compact, and thus easier to install in a car. It would also avoid the problem of the center casing becoming too complex. There would be fewer assembly and disassembly processes, and the turbine would be easier for maintenance. This variable-capacity turbine has nozzle drive members for the nozzles which is connected to an actuator that causes the drives member to rotate around the shaft turbine; and a nozzle adjustment mechanism which includes a number of connectors to link the nozzle drive members to the nozzle vanes. The nozzle adjustment mechanism, which comprises the nozzle drive member and the connectors, is installed in the link chamber provided inside the scroll, and the link chamber providing the nozzle adjustment mechanism is provided at the gas outlet side of the nozzle vans.
