The discharge ports 53 and 54 are for supplying air to the air supply pipe 57 via the discharge check valves 53 a and 54 a and the discharge pipes 55 and 56.

  Air is supplied from the pipe 57 to the air nozzle by advancing and retracting the piston 58 via the piston rod 58a. When the piston 58 moves to the left in the figure, the check valves 52a and 53a are opened and the check valves 51a and 54a are closed. When the piston 58 moves to the right in the figure, the check valves 51a and 54a are opened, and the check valves 52a and 53a are closed.

  FIG. 7 is a partial sectional view showing a state in which the air nozzle 41 is provided integrally with the nozzle body 10b of the cleaning nozzle 10 of FIG. 2, and FIG. 8 is a partial perspective view of FIG.

  The air nozzle 41 extends to the tip along the rear surface of the nozzle body 10b, and further stands up along the tip surface of the nozzle body 10b. The injection port 41a at the tip of the air nozzle 41 is close to the injection port 10c of the cleaning nozzle 10, and the injection port 10c and the injection port 41a are oriented in the same direction. The air nozzle 41 is provided integrally with the nozzle body 10b by ultrasonic fusion or the like.

  A lid member 41b is attached to the injection port 41a at the tip of the air nozzle 41 via a hinge.
