Abstract
A manufacturing method for manufacturing a component part for a variable capacity turbine, and the structure of a nozzle driving member, will simplify the structure of the component parts for the adjustable nozzle mechanism, the manufacturing work, which results in lowering the manufacturing count and cost as well as the number of component parts, and in lightening the weight of the variable capacity turbine. In order to manufacture the component parts for a radial-flow variable capacity turbine, in which 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, of which the angle is adjustable by an adjustable nozzle mechanism, for rotating a turbine rotor, this manufacturing method has a column shaped connecting pin formed as a single structure with a plate member by pressing, or by precision molding by partially forcing the surface of the plate member to protrude in a column shape.
