PROBLEM TO BE SOLVED: To simultaneously connect pipes constituting an observation window washing means and a fluid spraying means by disposing a single connection part in a connector of a universal cord of an endoscope to which the observation window washing means and the fluid spraying means are connected. SOLUTION: An air feeding path 15 and a liquid feeding path 16 of the washing means and a spray path 25 of the fluid spraying means are connected to through paths 23a-23c of the duct connection part 23 disposed in the connector 17 of the universal cord 3. A connection port 29 to which a connection part 28a of a fluid feeding pipe 28 is disposed in a pipe connection member 22 disposed at the distal end of a double flexible tube 21 of a washing liquid pipe 21a and a pressure pipe 21b. Paths 34a-34c communicating with the washing liquid pipe 21a, the pressure pipe 21b and the fluid feeding pipe 28 are disposed in a connection part body 31 of the pipe connection member 22. When the pipe connection member 22 is connected to the duct connection part 23, the through paths 23a-23c communicate with the paths 34a-34c respectively. COPYRIGHT: (C)2009,JPO&INPIT
