CABLE STRUCTURE CAPABLE OF MAINTAINING BELT ELEMENT HORIZONTALLY WITH MAIN BODY

摘要

PURPOSE: A cable structure is characterized by connecting a belt element to a displacement element and an actuator body with a fixed end and a movable end and preventing the belt type belt element from bending downward by self weight thereof because of forming the belt element into a belt type when the movable end is displaced according to displacement of the displacement element. CONSTITUTION: A cable structure comprises: a fixed end part(26) fixed on an actuator body(22); a movable end part(34) installed on a displacement element(20) capable of being displaced in an axial direction of the actuator body(22); and a belt element(25) installed on the fixed end part(26) and the movable end part(34) and connected with a rotatory element rotatably-supported on the fixed end part(26). The cable structure is operated by the steps of: rotating the rotatory element connected with the belt element(25) when the movable end is displaced according to displacement of the displacement element; and bending an axis of the belt element(25) based on a horizontal plane.
