PROBLEM TO BE SOLVED: To provide a bending push/pull function structure which can perform push-drive and pull-drive in a tip motion even in a curved or bent state, and can obtain the same drive forces in the push drive and also in the pull drive.SOLUTION: A bending push/pull function structure comprises: a bendable coil-shaped member 1 a flexible rope 2 which is inserted into an inside diameter of the bendable coil-shaped member the flexible rope 2 which is inserted into the inside diameter of the bendable coil-shaped member 1 at both ends of the bendable coil-shaped member 1 a one-end drive connecting member 3 and the other end drive connecting member 4. The flexible rope 2, the one-end drive connecting member 3 and the other end drive connecting member 4 are fastened to one another, and a push-side drive force can be obtained by pushing the bendable coil-shaped member via the one-end drive connecting member 3 and the other end drive connecting member 4.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】先端動作は、湾曲、あるいは屈曲状態でも押駆動、引き駆動が可能で且つ押駆動と引き駆動ともに同じ駆動力が得られる、屈曲押引き機能構造体を提供することにある。【解決手段】屈曲可能なコイル状部材1と、前記屈曲可能なコイル状部材の内径に貫通された可撓性ロープ2と、前記屈曲可能なコイル状部材1の両端に屈曲可能なコイル状部材1の内径に貫通された可撓性ロープ2と、一端駆動接続部材3と、他端駆動接続部材4、とを配し、可撓性ロープ2と、一端駆動接続部材3と、他端駆動接続部材4とを固結を形成し、屈曲可能なコイル状部材を一端駆動接続部材3と、他端駆動接続部材4を介して押圧することにより、押側の駆動力が得られる。【選択図】図1
