Abstract
The present invention provides an intake control device that appropriately restricts the flow of intake air when a valve body is set to a restriction position while the valve body is smoothly operated. The valve body is configured such that it is supported so as to be capable of swinging with respect to a sleeve, and when the valve body is set to the restriction position, a main valve portion of the valve body is lifted upward from a bottom plate, and a secondary valve portion of the valve body is sunk into an accommodating space of the bottom plate. In the accommodating space, a stepped portion that allows outward displacement from an inner surface of the sleeve is formed, and a seal portion that is brought closer to the stepped portion when the valve body is set to the restriction position is formed in the secondary valve portion.
