Abstract
An air conditioner outlet vent device in which one of a blade and a housing is molded as a primary molding having a shaft hole by primary injection using a first synthetic resin, the other is molded, within a secondary mold die where the primary molding has been set, as a secondary molding having a support shaft by secondary injection using a second synthetic resin so that the shaft hole and the support shaft are fitted together at the same time as they are molded, thereby enabling the blade to pivot within the housing. The first and second synthetic resins are of the same synthetic resin system, and an additive for suppressing shrinkage in cooling and solidifying it after injection molding is added to the first synthetic resin so that the percentage mold shrinkage of the shaft hole becomes smaller than that of the support shaft.
