PROBLEM TO BE SOLVED: To provide a cleaning device for a discharge nozzle which can sufficiently ensure cleaning effect by properly arranging a plurality of elements having a cleaning action. SOLUTION: The discharge nozzle 1 is installed so as to freely go up and down. Cleaning members 5, 6 are installed back and forth on a slide base 4 freely traveling along the lengthwise direction of the discharge nozzle. Each cleaning member comprises an elastically deformable main blade part 7 having a shape formed along the outline of a lip part 3 of the discharge nozzle and slidably contacting with the lip part by descending of the discharge nozzle, a pair of jet nozzles 8 disposed in front of the main blade part so as to hold the lip part from both sides and jetting a washing liquid toward the lip part, and a suction part disposed adjacent to the main blade part and sucking the washing liquid. A pair of sub-blade parts 10 disposed on the slide base so as to hold the lip part from both sides between the cleaning members, flexibly deformable so that they can be curved forward in the traveling direction of the lip part, and slidably contacting with the lip part by descending of the discharge nozzle.
