Verfahren zur Herstellung eines Drosselklappenstutzens einer Brennkraftmaschine und nach diesem Verfahren hergestellter Drosselklappenstutzen

摘要

A worker inserts a correcting pin into bearing members. Then, a cylindrical portion and retaining portions are molded together into an integrated resin unit. After finishing the molding operation, the worker extracts the correcting pin from the bearing members and subsequently inserts a throttle shaft into the bearing members. Accordingly, an axial center of the bearing member accurately agrees with an axial center of the bearing member. Then, the worker fixes a throttle valve to the throttle shaft.
