PROBLEM TO BE SOLVED: To facilitate suspending work by suspending and supporting the suspension chute of an upper opening on a guide rope suspended between a main tower side and a bridge girder side, feeding a strand in sequence from one end side of the chute, and guiding it to the other end side. SOLUTION: Each strand is suspended into the through hole of a fixing section 2a via a suspension chute 4 suspended between the fixing sections 2a so that the strand can be stretched and extracted from an opening section. When a lead body is fitted at the tip section of the strand, the release of the strand from the chute 4 is prevented by the lead body even when the strand is warped and bent when it passes through the chute 4. The whole suspension chute 4 is flexibly warped between the fixing section 2a on the main tower 2 side of a diagonal suspension bridge 1 and the fixed section 2a of a bridge girder 3 side. An unreasonable load by the weight of the strand at the head/tail connection portion of the single chute is excluded, and the work efficiency can be improved.
