PROBLEM TO BE SOLVED: To uniformly spray a liquid by periodically moving a spray nozzle train constituted of a plurality of spray nozzles arranged linearly in the prescribed plane. SOLUTION: A plurality of spray nozzles 3-1, 3-2... are linearly provided on a spray bar 4 to form a spray nozzle train, the bar 4 can be periodically moved on a circular, elliptical, oblong or polygonal locus in the horizontal plane parallel with the spray nozzle train, and this liquid spraying device 1 for the road surface is fitted to a work vehicle 2. The spray nozzles 3-1, 3-2... have a flat spray pattern as required, and the flat plane has an angle in the range of 0-90 deg. in the direction of the nozzle train. The bar 4 may be periodically moved on a desired locus in the vertical plane parallel with the spray nozzle train. When (n) spray nozzle trains are provided, the nozzle trains are moved at the phase difference of 360 deg./n. A liquid material can be sprayed highly uniformly.
