A wire rod container with a substantially W-shaped radial cross section that is spirally wound while being spirally wound. A wire rod such as a welding wire, which is supplied downward along the central axis direction, is stored with the spiral outer peripheral side in contact with the inner peripheral surface of the outer cylindrical portion and the inner cylindrical portion entering the spiral inner peripheral side. Although the outer cylindrical portion 2 and the inner cylindrical portion 3 are conventionally stored in a distributed manner along the circumferential direction of the inner cylindrical portion 2, the inner cylindrical portion 3 and the inner cylindrical portion 3 are inserted in the outer cylindrical portion 2 in the same manner as shown in FIG. The outer cylinder portion 2 and the inner cylinder portion 3 are arranged in a core shape.
A lower end side of the wire rod storage container A having an annular wire rod storage portion 1 formed between the outer tubular portion 2 and the inner tubular portion 3 is connected to the outer tubular portion 2 by connecting the outer tubular portion 2 with the annular bottom plate portion 4. By arranging the cylinder axis Y so as to be parallel to the spiral center axis X around which the wire W is spirally wound, and by rotating the wire storage container A around the cylinder axis Y, the spiral center While the shaft core X is relatively rotated along the circumferential direction of the wire rod storage unit 1, the spirally wound wire rod W is supplied to the wire rod storage unit 1 along the spiral central axis X direction, and is supplied.
