PURPOSE: An anti-drooping device for a roll shaft and a mounting structure thereof are provided to reuse the roll shaft because a roller is replaced by releasing the spiral coupling of the anti-drooping device. CONSTITUTION: An anti-drooping device for a roll shaft comprises a central bar(30), an elastic spring(40), a first spring support(60), a second spring support(50), and a fastening unit. The second spring support is fixed on one end of the central bar and passes through the elastic spring. The fastening unit fastens the first and second spring supports so that the compressed state of the elastic spring can be maintained by the first and second spring supports. |
