PROBLEM TO BE SOLVED: To provide a yarn storage device, a yarn take-up unit, and a yarn take-up machine capable of rotating a yarn storage roller stably.SOLUTION: In a yarn storage device 11, a first drive part 50 comprises: a first stator 51 located inside a yarn storage roller 40, extending along a rotary shaft direction of the yarn storage roller 40, and disposed so as to be coaxial with a rotary shaft; and a first rotor 53 fixed inside the yarn storage roller 40 at a position surrounding the first stator 51. A second drive part 70 comprises: a second stator 71 located inside the yarn storage roller 40 and fixed to the tip of the first stator 51; and a second rotor 72 fixed to a yarn threading member 60 and located inside the second stator 71. At least two bearing members 55 and 56 for allowing the yarn storage roller 40 to rotate freely with respect to the first stator 51 are disposed between the first stator 51 and a support part 42.SELECTED DRAWING: Figure 3 |
