In addition, the finger or the like holding the nut body 41a is less likely to come into contact with the column clamp device 5, and the operability is improved.

  After adjusting the height of the column clamp device 5 by rotating the height adjustment nut 41, the height adjustment nut 41 is rotated by tightening the lowering prevention nut 42 toward the height adjustment nut 41 side. 5 and the load of the camera C attached thereto is prevented from unintentionally descending. After the lowering prevention nut 42 is tightened, the column clamp device 5 is also finally tightened to the column P. In this manner, the height adjusting jig 1 for the strut mounting tool of this embodiment is used.

  According to the height adjusting jig 1 for the strut mounting tool of this embodiment, the relative position of the height adjusting nut 41 with respect to the clamp portion 2 attached to the strut P is raised and lowered by turning the height adjusting nut 41. To do. For this reason, fine adjustment of the height of the column clamp device 5 with which the height adjustment nut 41 abuts and the camera C attached thereto can be easily performed.

  In the present embodiment, the camera C is used as the device or the like attached to the column clamp device 5, but the device or the like attached to the column clamp device 5 using the height adjusting jig 1 of the present invention is this. Not limited to. Further, a thrust bearing may be provided at the upper end edge of the height adjustment nut 41.
