PROBLEM TO BE SOLVED: To provide an excellent material that enables fingers to bend and stretch by solving the problems of which simply imitate human fingers by aiming at a single axial joint as if they sit in a pulley-like saddle with no shaft. SOLUTION: Unlike the structure of a human finger, a single axial joint (hinge joint) (4, 5, 6) is achieved by inserting a shaft (7) in each joint as an axis for bending and stretching, because the finger is easily secured the side stability for bending and stretching even when not accompanied by ligament-like tissues. Further, a material with low friction and excellent antitension properties is used to produce an artificial tendon (8, 9, 10, 11) by suturing a stretching tendon with a bending tendon on the somatic side.
