PURPOSE:To prevent the dropping of the cleaning water remaining in a suction nozzle by allowing a communicating path between the inside of the nozzle and the external air to remain in an attraction part of a reaction bead. CONSTITUTION:A small projection 11 on the inside surface of the attraction part 10 forms the communicating path (w) for communicating the inside cavity of the suction nozzle 1 with the outside when the reaction bead (a) is attracted thereto. A notch 12 is provided to the circumferential wall of the part 10 as an inlet of the path (w). A dispensing nozzle 2 is in common use as an air feed nozzle as well and the nozzle 1 is disposed coaxially with only the nozzle 2 therein. The cleaning water in the hole is sucked and is recovered into a tank when the cleaning water from the nozzle 2 is stopped upon ending of the cleaning and the nozzle 1 is inserted into the hole. The bead (a) arriving at the end is attracted to the attraction part of the nozzle 1. The path (w) is formed at this time and the cleaning water remaining in the hole is sucked into the nozzle 1 and is thus thoroughly removed. Furthermore, the cleaning water in the nozzle 1 is recovered into the tank. The remaining cleaning water is thereby completely recovered and the dropping thereof is prevented. |
