PROBLEM TO BE SOLVED: To provide a flexible tube part of an endoscope which does not require a large force to bend the flexible tube part when the flexible tube part is bent at a small bending radius, has good operability, and reduces the burden on a patient, and to provide an endoscope having the flexible tube part.SOLUTION: The flexible tube part 25 has a spiral tube 81, a front side joining tube 111 provided on a distal end 81a side of the spiral tube 81, and a back side joining tube 121 provided on a proximal end 81b side of the spiral tube 81. The spiral tube 81 can move in an axial direction of the spiral tube 81 relative to at least one joining tube among the front side joining tube 111 and the back side joining tube 121.COPYRIGHT: (C)2013,JPO&INPIT【課題】 可撓管部を小さな湾曲半径で曲げる際にも、可撓管部を曲げるための大きな力を必要とせず、操作性が良く、患者への負担を減少できる内視鏡の可撓管部と、この可撓管部を有する内視鏡とを提供すること。【解決手段】 可撓管部25は、螺旋管81と、螺旋管81の先端部81a側に配設される前側接続管111と、螺旋管81の基端部81b側に配設される後側接続管121とを有している。螺旋管81は、前側接続管111と後側接続管121との少なくとも一方の接続管に対して、螺旋管81の軸方向に移動可能である。【選択図】 図3B
