PROBLEM TO BE SOLVED: To disuse a wire, to reduce a number of component, reduce a weight, a size, and cost, and easily approach to an affected part.SOLUTION: A manipulator comprises a flexible operation body which deforms a leaf spring by pressing and pulling the leaf spring, and operating an operation part 17 at a high freedom degree. A first flexible operation body 49 comprises: a rectangular lateral leaf spring 57； a curved vertical leaf spring 59 which stands and which has a plate surface being vertical to a plate surface of the lateral leaf spring 57, whose base end is connected to one end of the lateral leaf spring 57 in a longer direction, which protrudes to one side of a plate width direction of the lateral leaf spring 57, extends along a longer direction of the lateral leaf spring 57, and a tip end of an extension direction is an R part 65 which is bent in a direction opposite to the protrusion direction； a shaft body 61 to whose outer periphery, a tip end part of the R part 65 is connected and which is rotatable and which is supported by a rotation center 67 which is vertical to the plate surface of the lateral leaf spring 57； and the operation part 17 provided on an outer periphery of the shaft body 61 in a manner of protruding to outside of a rotation radius.SELECTED DRAWING: Figure 4【課題】ワイヤーを廃止でき、少ない部品点数で小型化、軽量化、コスト低減が可能であり、しかも、患部への容易なアプローチが可能となる。【解決手段】板ばねの押し引きにより板ばねを変形させて作動部１７を多自由度で動作させる可撓作動体を有するマニピュレータであって、第１可撓作動体４９は、矩形状の横板ばね５７と、横板ばね５７の板面に垂直な板面を有して起立し横板ばね５７の長手方向一端に基端が接続され横板ばね５７の板幅方向の一方に突出するとともに横板ばね５７の長手方向に沿って延在し延在方向先端が突出の方向と反対方向に曲がるＲ部６５となる湾曲縦板ばね５９と、Ｒ部６５の先端が外周に接続され横板ばね５７の板面に垂直な回転中心６７で支持されて回転自在となる軸体６１と、軸体６１の外周に回転半径の外側に突出して設けられる作動部１７と、を設けた。【選択図】図４
