PROBLEM TO BE SOLVED: To prevent a control wire from coming in slide contact with a slide guide and reduce a control torque to bending of an angle portion when the control wire is pushed and pulled by guiding the control wire into the slide guide by a roller. SOLUTION: As control wires 12a and 12b engage with the outsides of rollers 20a and 20b, namely the mutually opposite sides in an interval from a take-up wheel 11 and a slide guide 13, the control wires 12a and 12b are guided out from the take-up wheel 11, then moved to the direction of separating once from each other, and turned in the direction of approaching each other from the engagement portion of the rollers 20a and 20b, and the angles of the control wires 12a and 12b after this turnabout are almost identical to that of the slide guide 13.
