Then, the movable piece on the upstream side in the traveling direction is rotated in the opening direction, and a ram pressure corresponding to the traveling speed of the vehicle is obtained to adjust the amount of air intake. If the ram pressure cannot be expected when the vehicle stops, the movable pieces are rotated in the opening direction to increase the opening amount, and a sufficient amount of air is taken in by the small fan installed for low ram pressure. When the ventilation opening is used as an air outlet, the flow of air flowing along the outer surface of the vehicle body around the ventilation opening is reversed. In this case, make each movable piece protrude greatly into the outside air flow and increase the negative pressure at the air discharge port to increase the exhaust flow rate, or rotate each movable piece in the opposite direction to reduce the negative pressure at the air discharge port. Since the size is reduced and the exhaust flow rate is reduced, the same configuration can be used for the air inlet and the air outlet, which has the effect of reducing costs.
