PROBLEM TO BE SOLVED: To provide an inexpensive spraying apparatus having a simple structure and easily, rapidly and vertically moving a tank by easy manual operation. SOLUTION: The spraying apparatus is mounted on a rotary 2 of a self-propelled working vehicle and formed of a tank 4 for housing a material to be sprayed in the interior thereof, a spraying mechanism 5 installed in the lower part of the tank 4 and a spraying hose 6 mounted in the lower part of the spraying mechanism 5. The tank 4 is freely shakingly mounted in the rotary 2 so as to be vertically movable while maintaining a horizontal posture with a parallel link mechanism 20. Furthermore, the parallel link mechanism 20 is equipped with an elastic member 21 for applying the elasticity in the standing direction to the parallel link mechanism 20 during standing and rotation thereof.
