Abstract: Disclosed is a vehicle passage control device capable of suppressing damage and breakage of an opening/closing bar thereof to the minimum, and suppressing damage and the like of a vehicle to the minimum even if the vehicle collides with the opening/closing bar. The vehicle passage control device is a vehicle passage control device in which an opening/closing bar 12 that regulates passage of a vehicle is provided, the vehicle passage control device being installed at a passage gate of an entrance or exit of a toll road or the like. The vehicle passage control device performs opening/closing control for the opening/closing bar 12 to rotationally move and upspring obliquely upward in front in a passing direction of the vehicle. An inclined angle ? at which the opening/closing bar 12 rotationally moves and upsprings obliquely upward remains within a range from approximately 25 degrees to approximately 55 degrees with respect to a road surface.
