PROBLEM TO BE SOLVED: To provide a spraying work vehicle capable of preventing a side spraying boom from being unexpectedly slipping off, even when vibration occurs in case of folding the boom during traveling of the vehicle. SOLUTION: The spraying work vehicle has a central spraying machine frame 27 on a front part of a machine body, wherein the central spraying machine frame 27 is equipped with a central spraying pipe 35 and has a width equal to a width between right and left ends of the machine body, a side spraying machine frame 39 equipped with a side spraying pipe 48 is mounted on the central spraying machine frame 27 so as to be rotatable on an inclined axis 41 in such a manner that the side spraying pipe 48 is changed over between a wide-width spraying work state of being approximately linearly extended to both of right and left ends of the central spraying pipe 35 and a narrow-width stored state of being moved toward a side rear part of the machine body, and a locking device 50 composed of a fastening metal fitting 51 which receives the side spraying machine frame 39 in the narrow-width stored state and a locking metal fitting 52 which closes an inlet thereof is mounted on the frame 39.
