置。 In an intake passage control device in which a passage switching valve installed in the middle of an engine intake passage and a driving means for driving the switching valve are connected via a rotating shaft penetrating the passage wall, the passage is arranged so as to surround the rotating shaft. An annular sealing chamber is formed in the wall, and an annular sealing member that comes into elastic contact with the rotating shaft is held in the sealing chamber at its outer periphery, and the sealing member is in contact with a soft resin layer located on the driving means side. It has a multilayer structure consisting of a highly elastic material layer located on the passage side, and the inner peripheral edge of the soft resin layer contacts the rotating shaft at a position deflected in the direction of the intake passage than the outer peripheral part due to elastic deformation. An intake path control device for an internal combustion engine, characterized in that the seal chamber is formed with a seating surface that prevents the seal member from deforming toward the driving means.
