The extra lengths 30a and 31a at the ends of 1 ... Are made into an endless loop shape as shown, and the other ends are left independent.
The form shown in FIG. 6 is suitable for a site having a large impact force.

Further, as compared with the case of a single large-diameter rope material, the contact area with the shock-absorbing tool is increased, so that there is an advantage that sliding resistance is also increased. Further, in the case of FIG. 6 as well, as in the case of FIG.
Functions as a stopper that restricts the loop-shaped extra length portions 30a and 31a from coming off, and thus the number of component parts can be reduced.

な現場に最適である。<A> Conventionally, one shock absorber was used to grip two rope members on the left and right. In the case of this gripping method,
Since the left and right ropes are gripped with equal force, there is a disadvantage that the gripping force of the left and right rope members cannot be individually set when the span length of the support column changes. The present invention is suitable for such a site because the gripping force of the rope can be set individually.

By grasping the end portion of the rope member by the cushioning tool, the rope material can be surely prevented from coming off, and the exclusive stopper for preventing the pulling-out can be omitted. Therefore, the dedicated stopper can be omitted, and the number of component parts of the fence can be reduced.
