Intake Control Device
Abstract: To provide an intake control device that more efficiently captures dust in a bypass passage and has less deterioration in performance with respect to dust accumulation. An intake control device 1 includes a bypass passage 5 and a bypass valve 10 arranged in a valve hole 8 to adjust an amount of intake air flowing through the bypass passage 5 by adjusting a cross-sectional area of the bypass passage 5. In the bypass valve 10, when seen from the extension direction of the valve hole 8, an extended bottom portion 23 is formed in a range of a partition wall 21 where a valve-side engagement portion 17 is arranged as a recess recessed closer to one side than the other surface on the other side of the partition wall 21.
