As can be seen from FIGS. 3 and 4, the fastening means 14 is one of the sandwiching members 11 and 12 that are two members adjacent to each other in the circumferential direction of the support column 1. A male screw member 20 attached to the end opposite to the intermediate member 13 side, a nut 21 screwed into the male screw member 20, and a side opposite to the intermediate member 13 side of the other clamping member 12 The male screw member receiving portion 22 provided at the end includes the male screw member receiving portion 22, and the male screw member receiving portion 22 of the present embodiment is coupled to the sandwiching member 12 by welding or the like with a member other than the sandwiching member 12. As a result, the pinching member 12 is provided.

  The male screw member 20 is attached to the sandwiching member 11 such that the male screw member 20 is rotatable in the horizontal direction around one end of the male screw member 20. In order to perform the attachment, a rotation center shaft 23 whose axial direction is parallel to the length direction of the support column 1 is inserted into a hole formed in one end of the male screw member 20. 23 is also inserted into a hole formed in the sandwiching member 11. The rotation center shaft 23 according to the present embodiment is a shaft portion of a bolt 24A, and a nut 24B (see FIGS. 3 and 4) is screwed to the tip of the shaft portion of the bolt 24A.

  Further, since the male screw member receiving portion 22 provided on the sandwiching member 12 has an inverted L shape as shown in FIGS. 3 and 4, Thus, it has an opening 22A that opens toward the outer diameter direction of the column 1.

  When attaching the detachable fitting 10 according to the present embodiment to the column 1, first, as shown in FIG. 4, the two clamping members 11, 12 are attached to the intermediate member 13 with the shaft member 15 as the center.
