2 flows down uniformly in the inward direction and accumulates at the coating material outlet 7. When the coating material outlet shutter 8 is opened, the coating material 4 uniformly and quantitatively flowed down by the rotating bodies 1 and 2 is moved downward by the cylindrical brush rotating body 1 and the cylindrical drum rotating body 2. By the action of centrifugal force and repulsive force due to rotation, etc., uniform atomization spray (4a) is applied to the entire width of the two rotating bodies 1 and 2 to strike the road surface GL, and the coating film 11 is adhered to form a uniform road marking paint. Is what you can do. When the coating material outlet shutter 8 is closed, the coating material is blocked from flowing into both rotating bodies, and the injection by the rotating bodies 1 and 2 is blocked. Stops and the road marking painting can be stopped.
