a first frame unit that is provided in plural and are installed along an edge of a road; and
a first injection unit that is installed on the first frame unit and that injects air to the first frame unit side that the first injection unit faces, to form a first air barrier for blocking inflow of fog to the road,
wherein the first injection unit comprises a first air blast unit that inhales outside air, and a first air knife unit that is installed along a longitudinal direction of the first frame unit and that receives the outside air from the first air blast unit and forms the first air barrier by injecting the received air,
wherein the first air knife unit includes a first base unit in which the air received from the first air blast unit flows into and a first cover unit that is installed on a surface of the first base unit,
wherein one end of the first base unit is tapered with a first angle and one end of the cover unit facing the one end of the first base unit is tapered with a second angle that is larger than the first angle.
