を特徴とするワイヤ駆動装置。[Claims for Utility Model Registration] A screw-type flexible wire connected to a load is passed through the hollow rotor shaft of the drive motor, and this wire is attached to the outer peripheral surface of the wire core material with a substantially circular cross section. The rotor shaft is formed by providing protruding teeth on the outer periphery of a substantially semicircular shape at a certain pitch, and meshing the protruding teeth on the outer periphery of the wire with a female thread provided on the inner circumferential surface of the rotor shaft. A wire drive device for moving the wire in the axial direction by rotation of the wire drive device, wherein the cross-sectional shape of the thread groove of the female thread portion is a semicircular shape that matches the cross-sectional shape of the outer peripheral protruding tooth. .
