That is, the positioning can be performed steplessly. 5B, 6C, 6B, and 6C, the lower end portion 8E of the holding rod 8 is always the bottom portion of the arm 4 in the middle of standing and in the vertical posture. Press to 41.
Moreover, as can be seen from FIG. 1, the hole inner peripheral surface 10A of the wire winding body 10 gives the holding rod 8 a force to tilt its upper end radially inward, so that the state of FIG. The holding rod 8 does not fall inward in the radial direction. Moreover, the base end 9 of the holding rod 8 is strongly pressed (hooked) from below and above by the bottom 41 and the locking inner flange 43, and the holding rod 8 is unexpectedly moved radially inward. The radial inward position can be maintained without being displaced (moved).

Next, other embodiments shown in FIGS. 7 to 11 will be described. The same reference numerals are the same as those described in FIGS. 1 to 6, but differences will be described below.
That is, the holding rod 8 is inserted into the outer end opening 45 of the arm 4 in the horizontal posture, and the holding rod 8 is also used as an arm extension member 50 that extends the length of the arm 4.

Also, on the holding rod 8 in the horizontal posture, ride on the upper surfaces of the left and right inner collar portions 43 and 43 (slidably) as shown in FIGS. 8 and 10 from the proximal end to the middle in the radial direction. A wide belt plate 13 is attached to prevent the holding rod 8 from being inclined downward from the radial center to the tip.

As shown in FIG. 3, the arm 4 is placed on the upper surface of the annular turn wheel 2 so as to be placed and separated, and does not use a connecting tool such as a bolt. The axial center L ₂ and the axial center of the radial main body 5 are displaced from each other. In some cases, when the electric wire 10C is pulled out strongly, the radial main body 5 and the electric wire winding body 10 are attached to the annular turn ring 2. On the other hand, it may slide horizontally and fall off. However, in the present invention, as shown in FIG. 3, a positioning protrusion 6 (inverted L-shaped) that can be locked to the outer peripheral edge 2 </ b> G of the annular turn wheel 2 is provided so as to protrude downward.
In FIG. 3, two or more positioning protrusions 6, 6 are arranged on each arm 4 so as to cope with various different general-purpose annular turn wheels 2.

Next, as shown in FIGS. 1, 2, and 7, the radial main body 5 is integrally provided with a bottomed short cylindrical portion 15 at a center position in plan view by welding or the like.
The bottomed shape of the short cylindrical portion 15 is also preferable when a round bottom plate having a through hole is used in addition to a round bottom plate that is completely closed.
A pipe material 16 (shown in FIGS. 1, 2, 3, etc.) can be inserted into the short cylindrical portion 15 from above, and as illustrated in FIG. When the inner diameter of the surface 10A is large, it can be omitted by applying the holding rod 8. However, for the inner diameter of the hole inner peripheral surface 10A of the wire wound body 10, the pipe material 16 is It serves to prevent radial misalignment.
When positioning the electric wire winding body 10 using the holding rod 8 in the standing posture (preventing displacement), the pipe material 16 may be removed.

Further, the arm 4, since lockable positioning protrusion 6 on the outer peripheral edge 2G of the annular turn wheel 2 is protruded downward with respect to the axis L ₂ of the annular turn wheels 2 The axial center (center point) of the radial main body 5 is not displaced, and the electric wire 10C can be pulled out smoothly.

  Further, the radial main body 5 is integrally provided with a bottomed short cylindrical portion 15 at a central position in a plan view, and has a smaller inner diameter of the inner circumferential surface 10A of the wire wound body 10. Or pipe material 16 for preventing radial displacement in the through hole of the electric wire drum to which the electric wire winding body 10 is attached can be inserted into the short cylindrical portion 15 from above. As a result, the holding rod 8 in the standing state can reliably hold the wire winding body 10 whose inner diameter of the hole inner peripheral surface 10A is medium to large as described above, and can efficiently pull out the wire 10C. The electric wire winding body 10 having a smaller inner diameter can be securely held and the electric wire 10C can be pulled out in the same manner, and can be used for a wider variety of electric wire winding bodies 10. In addition, when the wire drum is wound on a wire drum (generally used wooden) with a wire drum, if the through-hole of the wire drum is as small as several tens of millimeters, the pipe material 16 is inserted into the through-hole. And can efficiently draw out the electric wire from the electric wire drum.
