Abstract: A housing defines a bore in a tubular shape to draw intake air to an engine. A shaft is supported rotationally relative to the housing. A valve is located in the bore and affixed to the shaft. An electric actuator is configured to rotate one end of the shaft. A load generating unit is configured to apply a biasing load onto the shaft from the one end of the shaft toward the bore in a high-temperature state in which a temperature is higher than a predetermined temperature.
