ABSTRACT:
An intake control device for an internal combustion engine includes an intake air induction duct, a housing, a valve, and a gasket. The housing is received in a receiving chamber of the intake air induction duct. The valve is received in the housing for opening and closing an intake passage defined in the housing. The gasket is mounted on one of (a) a position between the intake air induction duct and the attachment surface, and (b) a position between the housing and a wall surface of the receiving chamber. The housing opposes the attachment surface and is spaced from the attachment surface by a predetermined clearance. The gasket has an elastic deformation portion that is positioned between the housing and the attachment surface.
