Abstract
A resin main body (3) defining a bore (7) through which intake air flows, and a valve body (60) having a shaft part (20) rotatably supported by the main body (3) and a valve part (4) for opening and closing the bore (7) of the main body (3) are provided. The main body (3) is molded with the valve body (60) inserted together with a pair of bearing sleeves (24). At the time of molding the main body (3), the bearing sleeves (24) are biased in a direction opposite to the flow of the intake air with the valve body (60) being positioned in place.
