To make it possible to perform high-speed winding, by reducing the weight of a moving body, wherein a winding nozzle, a slider member and a winding main shaft are integrally formed.

A moving body 10 comprising a winding main shaft 1, a winding nozzle 2, a slider member 3 and a weight 9 is guided with a straight advancing guide. The moving body 10 is driven by a motor 5 and a belt 8 for straight travelling and reciprocally moved in the direction of an axial line X. At the same time, the moving body 10 is reciprocally turned around the axial line X by another motor, and a wire is wound around a core 20. Then, the weight 9 is adjusted so that the acting wire L of driving force F by the belt 8 passes the center of gravity G of the moving body 10. The generation of couple of force in the moving body 10 is prevented by the driving force F, and the frictional force with the straight travelling guide is decreased. Thus, the guide part of the slider member 3 is shortened, and the light weight of the moving body 10 is achieved.
