Abstract
A boss is shaped in a tubular form and is injection molded integrally with a housing that forms a flow passage. A ring member is press-fitted to an inner peripheral wall of the boss. A shaft placed on a radially inner side of the ring member is configured to be rotated about a central axis. A movable valve is coupled to a portion of the shaft and is configured to adjust a size of a cross-sectional area of a passage opening at the flow passage. Each of gate marks of the housing is a trace of a site of the housing where molten resin is injected at a time of injection molding of the housing. Each of ribs radially inwardly projects from the inner peripheral wall of the boss and is placed at a corresponding location of the boss which is between adjacent two of the gate marks.
