Claims

[Scope of utility model registration request]

In an endoscope in which the proximal end of the insertion section is connected to the operation section main body via the insertion section connecting cylinder, the fixing structure between the insertion section connecting cylinder and the proximal end of the insertion section is as follows:
The insertion part connecting cylinder has a diameter that allows it to be inserted from the distal end side to the proximal end side of the insertion part, and the insertion part is inserted between the proximal end of the insertion part and the insertion side end of the insertion part connecting cylinder. A regulating part is provided to regulate the movement of the insertion part connecting cylinder, and the end of the restricted insertion part connecting cylinder on the insertion part side and the insertion part are connected by a fixing member. Endoscope.
