Claims

[Scope of utility model registration request]

Overlap the connecting protrusions provided on each segmental ring for forming the curved tube portion of the endoscope, and insert each into the connecting pivot shaft fitting insertion hole of each empty connecting piece that has been made reversible. In a connecting structure of joint rings for forming a curved pipe portion, each joint ring is fitted with a joint pivot shaft, and each joint ring is rotatable about the respective joint pivot shafts. The length of the pivoting shaft part of the mounting shaft is approximately equivalent to the total thickness of the overlapping connecting protrusions, and this is inserted into the connecting pivot shaft insertion hole of each overlapping connecting protruding piece. After the fitting and insertion, each connecting pivot shaft is welded to one of the overlapping connecting protrusions using laser light energy, etc., thereby connecting each joint ring. Connection structure of segmental ring for forming curved tube part of endoscope.
