PROBLEM TO BE SOLVED: To provide a chemical spraying apparatus for a speed-sprayer in which an operation for stoppage (or the cancel of stoppage) of spray to a partial area is simplified, operation efficiency is improved and defects of scattering of the chemical on an undesirable area and wasteful use of the chemical are avoided. SOLUTION: The chemical spraying apparatus for the speed-sprayer is provided with: a chemical spray mechanism 2 for spraying the chemical to a specified area in the spraying direction; a blocking cover 3 for blocking a partial area An in the specified area to restrict the spray of the chemical; and a cover moving means 4 for moving the cover selectively to a blocking position Xs for blocking the partial area An or to a releasing position Xr for releasing the blocking, and is further provided with a chemical supply interlocking means 5 for stopping the supply of the chemical to be sprayed on the partial area An when the blocking cover 3 is moved to the blocking position Xs side and for releasing the stoppage of the supply when the blocking cover 3 is moved to the releasing position Xr side.
