| 摘要 | The object of this invention is to propose a manufacturing method for manufacturing component part for the variable capacity turbine, and the structure of the nozzle driving member, which will simplify the structure of the component part for the adjustable nozzle mechanism, the manufacturing work which results in lowering the manufacturing count and cost, as well as the number of component part, and in lightening the weight of the variable capacity turbine. In order to manufacture the component part for a radial-flow variable capacity turbine, in which the actuating gas is forced to flow from a spiral scroll formed in the 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 the turbine rotor, this manufacturing method according to this invention is distinguished by the configuration in which a column shaped connecting pin is formed as a single structure with a plate member by a pressing, or a precision molding by partially forcing the surface of the plate member to protrude in a column shape. | ||||||
