PROBLEM TO BE SOLVED: To prevent loosening and uneven winding of a wire by reducing fluctuation of tension during winding. SOLUTION: The coil winding device is for causing the wire drawn out of a wire source to be wound on a workpiece by use of a nozzle unit having a nozzle. A tensioner 20 for applying a predetermined tension to the wire 5 supplied from the wire source to the nozzle 10 comprises a roller 23 for winding the wire 5 thereon, a guide means 21 for movably holding the roller 23, and a biasing means 25 intervening between the roller 23 and the guide means 21 for biasing the roller 23 in a first direction. The nozzle 10 is connected to the tensioner 20 to constitute the nozzle unit 9. |
