PROBLEM TO BE SOLVED: To certainly fix (n) types of bobbins with a common shaft by slidably providing a pressing plate on a sleeve and providing a spring for energizing this pressing plate to the bobbin side. SOLUTION: A bobbin fixing device can fix (n) types of bobbins 3, 3" with one shaft. A sleeve 5 and a rod 4 are stuck and fixed with a pin 6 by adjusting their lengths with relative shaft motion, and the bobbins are fixed by spring- energizing a pressing plate 7 attached to the sleeve 5 to the bobbin side with a spring 8. Therefore, a winder in which number of turns of a line and number of types of bobbins are increased acts more effectively. In the device, the structure becomes simple without requiring complication, preparation of many bobbins for bobbin size is not required, the operability is improved, and safety is high. Therefore, (n) types of bobbins can be certainly fixed with a common shaft.
