PROBLEM TO BE SOLVED: To prevent breakage of a connection port attachment member and an inner conduit member when an excessive load is applied on a member of an adapter connecting port such as a forceps port. SOLUTION: In a conduit connection device for an endoscope for connecting the adapter for sending of a solution or the like to the forceps port 12K, a rectangular part 12d having a periphery of a substantially regular tetragon is formed below a forceps port body 12, and an engagement hole 15d which has an inner periphery of a substantially regular tetragon and is configured to make the rectangular part 12d engage is formed below an attachment hole 15 on one resin holder 14. Then, a torque limiter mechanism by which the forceps port body 12 runs idle at a prescribed torque value or higher is configured by placing an elastic rubber 16 between the rectangular part 12d and the engagement hole 15d. The constitution in which elasticity is imparted to a side of the forceps port body or a side of the holder without providing the elastic rubber 16 can be achieved. COPYRIGHT: (C)2011,JPO&INPIT
