PROBLEM TO BE SOLVED: To provide a discharging device that prevents foam from liquefying and dripping from a nozzle hole and solidifying, when releasing a push-down head from push-down.SOLUTION: In a discharging device, an air introduction passage 65 for communication between an interior of an air cylinder 23 and an air-liquid mixing chamber 26 is formed between an extrapolation body 45 of an air piston 22 and a stem 12, and an air suction passage 60 for communication between the air introduction passage 65 and a nozzle hole 15 is formed between a push-down head 14 and a top end part 24 of the stem 12. The stem 12 includes: a first seal portion 71 which is alienated downward from the extrapolation body 45 by moving downward in accompaniment with push-down of the push-down head 14 in order to allow the air introduction passage 65 to communicate with the interior of the air cylinder 23; and a second seal portion 72 which abuts on the extrapolation body 45 from above by moving downward in accompaniment with the push-down of the push-down head 14 in order to block communication between the air suction passage 60 and the air introduction passage 65. |
