PROBLEM TO BE SOLVED: To provide an auxiliary water feeding device for an endoscope and an auxiliary tube unit without requiring long time for a drying step in the autoclaving process.SOLUTION: An auxiliary water feeding tube unit 10 has a water feeding device side connection means 11 connecting to a water feeding device body 1 and an endoscope side connection means 20 connecting to an endoscope 2 at both ends of a flexible tube 12 respectively. The endoscope side connection means 20 includes an endoscope side connection member 21 and opening/closing members 34, 39, 44 and 47. One end of the endoscope side connection member 21 is narrower than the other parts and constitutes a narrow end 28 to connect to the endoscope. The other end of the endoscope side connection member has inner conduits 23, 26, 28 and 32 connecting to one end of the flexible tube, and a communication passage 24 whose one end connects to a part other than the narrow end of the inner conduits and whose other end opens on the surface. The opening/closing members are relatively movable between a closing position to close an opening of the communication passage 24 and an opening position. |
