PROBLEM TO BE SOLVED: To obtain a tip connection structure of an endoscope insertion part having a reduced diameter.SOLUTION: There is provided a tip connection structure of an endoscope insertion part in which a bent pipe on the insertion part tip side is connected to a flexible pipe on the operation part side through a connecting pipe. A tip end face of a flexible pipe outer cover positioned on an outer periphery of the flexible pipe and a rear end face of a bent pipe outer cover positioned on an outer periphery of the bent pipe are faced to each other without overlapping each other in a radial direction on an outer periphery of the connecting pipe.SELECTED DRAWING: Figure 3 |
