In the valve device, the intake inner cylinder is provided with a protrusion that approximately follows the rotation locus of the outer periphery of the throttle valve in the rotation range near the closed position of the throttle valve, and the shape of this protrusion is determined when viewed from the rotation direction of the throttle valve. 1. An intake throttle valve device characterized in that a central portion thereof has a shape that substantially follows the outer periphery of the throttle valve over a larger rotation range than both side portions. (2) The shape of the protrusion in the intake throttle valve device according to claim 1 is such that both side parts as seen from the rotational direction of the throttle valve substantially follow the outer periphery of the throttle valve over a larger rotation range than the central part. An intake throttle valve device characterized by:
