The forwardly winding linear body and the reversely winding linear body are connected to the reciprocating body. The forward winder on winding rotation and the reverse winder on rewinding rotation rotate in synchronism and phase with each other in the same or reverse direction. The amount of winding the forwardly winding linear body by the forward winder and the amount of rewinding the reversely winding linear body by the reverse winder are equal to each other. The amount of rewinding the forwardly winding linear body by the forward winder and the amount of winding the reversely winding linear body by the reverse winder are equal to each other.
