Provided is an endoscope in which a bending portion and a flexible portion of an insertion portion are firmly joined in a separable manner. The piece 20 on the soft part side of the bending part 11 and the connection ring 29 of the soft part 12 are connected to each other by a clip 200 and a pin 201, and the piece 20 has a notch 217 extending in the axial direction from the end of the piece 20. The clip 200 is detachably attached to the fitted piece 20 and the connection ring 29, and each of the piece 20 and the connection ring 29 against relative movement in the axial direction between the piece 20 and the connection ring 29. The pin 201 is fixed to the connection ring 29, enters the notch 217 when the piece 20 and the connection ring 29 are fitted, and rotates around the axis between the piece 20 and the connection ring 29. Are engaged with each of the piece 20 and the connection ring 29 in the rotation direction.挿入部の湾曲部と軟性部とが分離可能に強固に接合された内視鏡を提供する。湾曲部１１の軟性部側の駒２０と軟性部１２の接続環２９とは、クリップ２００及びピン２０１によって互いに連結され、駒２０には、駒２０の端から軸方向に延びる切り欠２１７きが設けられており、クリップ２００は、嵌合された駒２０及び接続環２９に着脱可能に装着され、駒２０と接続環２９との軸方向の相対移動に対して駒２０及び接続環２９の各々と軸方向に係合し、ピン２０１は、接続環２９に固着されており、駒２０と接続環２９との嵌合に伴い切り欠き２１７に進入し、駒２０と接続環２９との軸まわりの相対回転に対して駒２０及び接続環２９の各々と回転方向に係合する。
