が形成されている。On the other hand, as shown in FIG. 1, the operating portion of the parent endoscope 3 is provided with a channel opening 8 that projects through the insertion channel 7. The insertion aid 1 is detachably attached and fixed to the channel opening 8 by a cylindrical fixing nut 2. The fixing nut 2 is screwed and connected to the outer periphery of the base 9 on the insertion assisting tool 1 side. The base 9 is fixed to the main body 10 of the insertion aid 1. Above the main body 10, a guide member 11 is mounted on the insertion channel 7 so that the center axis thereof is substantially aligned with the center axis. Further, an inner cylindrical portion 12 fitted inside the guide member 11 and an outer cylindrical portion 13 fitted outside the guide member 11 are provided.
The outer end portions are connected to each other to form a double cylindrical portion 14, and a chuck member 24 provided with an elastic member is connected to the double cylindrical portion 14. That is, the guide member 11 is sandwiched between the inner cylindrical portion 12 and the outer cylindrical portion 13 from inside and outside. Further, between the outer tube portion 13 and the inner tube portion 12, a spring member 22 is provided,
Further, the projection 15 on the guide member 11 side is provided on the outer peripheral side so as to be in sliding contact with the inner peripheral surface of the outer cylindrical portion 13. A projection 16 on the slide side is formed on the inner circumference of the open end of the outer cylinder portion 13, and this projection
Reference numeral 16 slides on the outer peripheral surface of the guide member 11. The outer cylindrical portion 13 of the double cylindrical portion 14 has an air vent hole 23
