Therefore, the rotation gear 63 can be easily cleaned and disinfected.
- the channel 73 extends from the outer surface of the operation unit 3 to the gear arrangement unit 138 on the outer periphery of the insertion unit 2. That is, both ends of the channel 73 are open to the outside of the insertion portion 2 and the operation portion 3. For this reason, even when the liquid flows into the channel 73, the liquid hardly stays in the channel 73. Therefore, it is not necessary to prevent the liquid from flowing into the channel 73 inside the insertion body 13. Since the waterproof elastic member is not provided, the friction acting on the linear member 83 and the tube base end portion 29 is reduced when the mounting unit 25 rotates.

Further, it is possible to appropriately cope with the problem of the first linear member 83A of the drive unit 113.
- the base end side ring 148 is fixed in a state where there is no gap in the rotating body 61. Accordingly, the mounting unit 145 rotates about the longitudinal axis C with respect to the insertion body 13 integrally with the rotating body 61 in accordance with the rotation of the rotating body 61. However, the base end side ring 148 is regulated so as not to move along the longitudinal axis C with respect to the insertion body 13.
- the fin portion 147 includes a metal core 151 that spirally extends along the longitudinal axis C, and a rubber portion 152 that is provided so as to cover the periphery of the metal core 151.
- the rotation is appropriately transmitted from the proximal ring 148 to the distal ring 149. Further, by covering the metal core 151 with the rubber portion 152, the metal core 151 having high hardness is prevented from being exposed.

That is, in the endoscope 1, when the insertion portion 2 is inserted into the lumen, an external force acts from the distal direction. The distal side ring 149 moves in the proximal direction by an external force from the distal direction. Thereby, the dimension from the longitudinal axis C to the outer peripheral end of the fin portion 147 is D7, which is larger than the dimension D5 in a state where no external force acts in a direction parallel to the longitudinal axis C. This makes it easier for the fin portion 147 to come into contact with the lumen wall inside the large intestine, inside the small intestine, and the like. For this reason, when the mounting unit 25 is rotated, the propulsive force acting on the insertion portion 2 in the distal direction increases. Therefore, the insertion property of the insertion part 2 in the lumen can be improved.
- the insertion portion 2 when the insertion portion 2 is removed from the lumen, an external force acts from the proximal direction.
- the proximal side ring 148 moves in the distal direction by an external force from the proximal direction.
- the dimension from the longitudinal axis C to the outer peripheral end of the fin portion 147 becomes D6, which is smaller than the dimension D5 in the state where no external force acts in a direction parallel to the longitudinal axis C. Therefore, the insertion portion 2 can be easily removed with the force in the direction parallel to the longitudinal axis C by the operator without rotating the mounting unit 25.

なお、第2の実施形態では、部材挿入部72にモータ75又は手動回転部材118が装着されているが、これに限るものではない。例えば、第1の変形例として図16に示すように、線状部材83が、部材挿入口71から操作部3の外部に延出されてもよい。本変形例では、操作部3の外部で、切替え接続部111により線状部材83とモータ75又は手動回転部材118とが選択的に接続される。
次に、本発明の第3の実施形態について、図17及び図18を参照して説明する。第3の実施形態は、第1の実施形態の構成を次の通り変形したものである。なお、第1の実施形態と同一の部分については同一の符号を付して、その説明は省略する。
なお、第3の実施形態では、中継外皮125により第2の外表面部128が形成されているが、これに限るものではない。例えば、第1の変形例として図19に示すように、湾曲部外皮45の外周部に、金属製のリング135を固定してもよい。この場合、リング135により、第1の外表面部127より摩擦に対する強度が高い第2の外表面部128が形成される。
次に、本発明の第4の実施形態について、図21及び図22を参照して説明する。第4の実施形態は、第1の実施形態の構成を次の通り変形したものである。なお、第1の実施形態と同一の部分については同一の符号を付して、その説明は省略する。
第4の実施形態の第1の変形例として、図23に示すように回転ギア63を備えるギアユニット110に、駆動ユニット113又は手動回転ユニット117が選択的に接続されてもよい。駆動ユニット113は、駆動部材であるモータ75と、第1の線状部材83Aとを備える。装着部である部材挿入部72にモータ75が装着された状態では、第1の線状部材83Aは、操作部3の内部及び挿入部2の内部を通って回転ギア63に向かって延設される。また、駆動ユニット113は、ギア配置部138で回転ギア63と第1の線状部材83Aとの間を接続する第1の切替え接続部141Aを備える。図24は、図23の24-24線断面図である。図24に示すように、第1の切替え接続部141Aは、ギア軸Rに垂直な断面において、回転ギア63の溝状部139に対応する略六角形状に形成されている。第1の切替え接続部141Aが溝状部139に挿入されることにより、回転ギア63と第1の線状部材83Aとの間が接続される。これにより、ギアユニット110と駆動ユニット113とが接続される。
次に、本発明の第5の実施形態について、図25乃至図27を参照して説明する。第5の実施形態は、第1の実施形態の構成を次の通り変形したものである。なお、第1の実施形態と同一の部分については同一の符号を付して、その説明は省略する。
