Abstract:
A manufacturing method for manufacturing a component part for a radial-flow variable capacity turbine, in which an actuating gas is forced to flow from a spiral scroll formed in a turbine casing to a turbine rotor in a radial direction through multiple nozzle vanes, which nozzle vanes have an angle that is adjustable by an adjustable nozzle mechanism, for rotating the turbine rotor, wherein, for manufacturing a connecting pin which transmits a driving force to an engaging counter member by engaging with a recess or a hole formed in the counter member out of the component part of the adjustable nozzle mechanism and a plate member connected to the connecting pin, said manufacturing method comprises:forming the connecting pin as a single structure with said plate member by partially forcing a surface of said plate member to protrude in a column shape.
