It is preferable that the amount of protrusion is adjustable. By doing this, when the heights of the pallets on which the original fabrics 100 are placed vary (see Fig. 8), the locking pieces 12 can be adjusted by adjusting the amount of protrusion of the locking pieces 12 from the underframe 4. It can be accurately positioned on the lower surface of the original fabric 100.

Under normal conditions, the lower end of the support column 42 of the underframe 4 comes into contact with the truck 1 and is locked by the hook 13, and by removing this hook 13, the lower end of the support column 42 of the underframe 4 can be rotated around the shaft 3 as shown by the imaginary line in FIG. The underframe 4 can be rotated and tilted by hand. In this inclined state, the original fabric locking piece 12 protrudes in the horizontal direction so that the lower end surface of the original fabric being stored can be scooped up by this locking piece 12.

The original fabric holder 10 includes a groove-shaped main member 10a, arcuate end members 14 attached to both front and rear ends of the main member 10a,
15, a pair of shafts 9 coupled to the respective side ends of the end members 14 and 15, and a support roller 8 externally fitted onto the shaft 9 so as to be rotatable and movable in the axial direction. have. Bearings 89 are attached to both ends of the support roller 8 between the shaft 9 and the shaft 9, as shown in FIG. I am making sure that the movement is carried out. Further, as shown in the imaginary line in FIG.
An appropriate spring may be placed on the outer periphery of the shaft 9 between the end of the support roller 8 and the end member 15.

Further, a reinforcing member 16 made of a pair of angle members is attached between both side ends of the end members 14 and 15, and a guide rod 11 extending downward is attached to this reinforcing member 16, and this guide rod 11 is attached to the underframe.
