However, in the conventional automatic fixing device described in the above-mentioned publication, the inclination (direction) of the cylinder cannot be adjusted in the state of being fixed to the collar 1a. That is, normally, the fixing device is fixed to the ribs (collars) of the body, but the amount of protrusion of the ribs is small, and it is difficult to fix the tubular body in any direction (see the above-mentioned publication and Examples).

Further, if the size (diameter) of the cable drum is different, the lead-out direction of the cable winding start end a ′ also differs, so that it is necessary to align the tubular body in the lead-out direction for each drum of different size. However, due to the small amount of protrusion of the rib and the difference in curvature of the rib, it is very difficult to deal with this.

For this reason, when the conventional automatic fixing device is attached, the direction in which the cable winding start end a ′ is led out does not match the direction of the tubular body, and the end may not be smoothly inserted into the tubular body. there were.

According to the present invention, if the orientation of the tubular body can be adjusted even after being attached to the collar, the tubular body can be guided to the outlet without being affected by the small amount of protrusion and the difference in rib curvature. Focusing on the correspondence, the challenge is to be able to adjust the orientation of the cylinder.
