Forming one curved portion 32, and further bending at a right angle to form a second spindle support portion 33. As can be seen from FIG. 4, the tips of the first spindle support portion 31 and the second spindle support portion 33 are both slightly inclined upward, and the inclination angle of the first spindle support portion 31 is the same as that of the second spindle support portion. It is smaller than the inclination angle of 33. The purpose is that the spindle inserted into the support portion of the spindle engages with the support portion by the weight of the bobbin tube and the spindle itself, and in that state, the above inclination angle is just an appropriate angle with respect to the direction of the yarn drawn from the spindle. Is to do.

Here, it should be particularly noted that the spindle support shaft 30 of the present invention has one curved portion 32, which allows the spindle support shaft 31 and the second spindle support portion 33 to be mounted on the spindle support shaft 31 and the second spindle support portion 33. The thread at the bottom of the installed spindle can be prevented from getting caught on the spindle support shaft 30 and the surface of the cloth can be kept beautiful without damaging the thread, and there is enough space to connect the upper and lower threads between the spindles. Is convenient for manual work.

Further, the spindle support shaft 30 has a square cross section, and both arm pieces 21 of the U-shaped clamp 20 are also provided with square square holes 22, respectively. If you insert it in 22, it will be fixed without rotating. Further, the pillar 100 has a rectangular cross section and is fitted into the U-shaped clamp 20.
