Abstract
The bending part of an endoscope is constructed in which plural joint rings are connected with each other. The adjacent joint rings are rotatably connected with rivets after overlapping a connecting part with another connecting part. A guide hole is formed at the inner head of the rivet, and a bend-control wire is inserted through the guide hole whereby the bend-control wire is guided. A notch and a hole are formed at the end and the base of the connecting part, respectively; therefor the bend-control wire is prevented from coming into contact with the connecting part.
