PROBLEM TO BE SOLVED: To provide a spraying device capable of automatically and reversibly rotating a spraying pipe within a fixed angle range and also capable of uniformly spraying spraying liq. even in long size feed pipe and also without interrupting farmwork, or the like. SOLUTION: In this spraying device, the spraying pipe 15 in which nozzles 23 and 24 are provided side by side at a desired interval is hung to a suspended supporting body 6 so that it reversibly rotates within a fixed angle range round the axial line and also the spraying pipe 15 and a fluid feed source 32 for supplying the spraying fluid consisting of the liq. such as water, a liq. fertilizer or a liq. chemical or a gas such as gaseous carbon dioxide are connected by a loosened flexible hose 25 at the vicinity of the spraying pipe 15 so that the reversal rotation of the spraying pipe 15 may be permitted.
