PROBLEM TO BE SOLVED: To provide a spraying apparatus in which a driving mechanism for opening and closing a shutter unit is improved. SOLUTION: In the apparatus, power for driving a stirring rotor 3, and that for closing and opening a movable shutter 2-1 of a shutter unit 2 are transmitted from one motor. The rotary axis 3-1 of the stirring rotor 3 and the output axis 4-1 of the motor 4 are connected with sprockets 15, 16 and a chain 17; and the rotary axis 3-1 and the movable shutter 2-1 are connected with a direction changing mechanism 5. The direction changing mechanism 5 comprises an output part 5-1 having a connection boss 18 on one of the eccentric sides of an eccentric can 20, an output transmitting link 5-2 having an engaging part 19 which engages with the connection boss 18 only during the reverse rotation of the output part, and a changing link 5-3 for changing horizontal motion in the longitudinal direction to the rectangular direction of the output transmission link. The movable shutter slides in the opening and closing direction of each spraying port, interlocked with the normal and reverse rotation of the changing link 5-3 in the horizontal direction.
