Abstract
An airflow control valve structure includes a metallic pivot shaft-and a valve body. The valve body includes a connection portion connected to the pivot shaft and a resin valve portion. The pivot shaft includes first and second pivot shaft side press-fit portions. The connection portion includes a first valve side press-fit portion formed integrally with the valve portion and a metallic fitting member including a second valve side press-fit portion. The first valve side press-fit portion is fitted to the first pivot shaft side press-fit portion at an angular position at which a phase of the valve portion is matched with a phase of the pivot shaft. The second valve side press-fit portion is fitted to the second pivot shaft side press-fit portion. The first pivot shaft side press-fit portion is longer than the second valve side press-fit portion.
