PROBLEM TO BE SOLVED: To provide a flexible tubular part for an endoscope, the flexible tubular part being small in an amount of flexibility of the flexible tubular part even when load is applied on the flexible tubular part in a straight state and becoming large in the amount of flexibility of the flexible tubular part when load is applied to the flexible tubular part in a bent state, and to provide an endoscope having the flexible tubular part.SOLUTION: The flexible tubular part 25 of the endoscope 1 has a helical pipe 31. The helical pipe 31 is formed from an adhering wound part 32 to at least part of which initial tension is applied, and a roughly wound part 33 disposed on at least one end of the densely wound part 32.COPYRIGHT: (C)2013,JPO&INPIT【課題】直線状態の可撓管部に荷重を加えても可撓管部の撓み量が小さく、撓んだ状態の可撓管部に荷重を加えると可撓管部の撓み量が大きくな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】内視鏡1の可撓管部25は、螺旋管31を有している。螺旋管31は、初張力が少なくとも一部に付与された密着巻き部32と、密着巻き部32の少なくとも一端に配設されている疎巻き部33とによって形成されている。【選択図】 図2
