Abstract
An active dual roll shutter apparatus for a vehicle has two lead screws rotated by power from a single motor. First and second roll screens are simultaneously operated upward and downward in opposite directions along the two lead screws to open a flow path when the lead screws rotate, thereby improving sealability of the flow path and aerodynamic performance of the vehicle.
