[Problems to be solved by the device]

 However, in this structure, even if the tightening screw 36 is tightened, the toothed washer 25 bites into the mounting portion 23 of the projector main body 22 because it is soft by aluminum die casting, but it is hard in the arm 30 because it is iron or stainless steel. So don't go too far. Therefore, when the projector is shaken or shocked due to vibration, wind, earthquake, or object collision, the toothed washer 25 slides on the surface of the arm 30 and the angle of the projector 20 is changed from the fixed position. It has the drawback of being out of alignment.

An object of the present invention is to provide a fixing structure that can surely fix a position where a lighting fixture such as a floodlight is once fixed so as not to shift due to impact, vibration or the like.
