PROBLEM TO BE SOLVED: To provide a roll supporting tool capable of suppressing an unwanted bulky state according to a number of piled steps of supported rolls. SOLUTION: When the number of piled steps of the rolls 90 is a middle number of piled steps smaller than a maximum number of piled steps, the roll supporting tool 10 bends an upper plate supporting board 41 in a plate supporting board 30 to a supporting plate 11 when the supporting plates 11 as many as the middle number of steps are piled up along a longitudinal groove 29. Thus, the entire roll supporting tool 10 is made lower than the case that the rolls 90 are piled up to the maximum number of piled steps. That means, the roll supporting tool 10 can suppress the unwanted bulky state according to the number of piled steps of the supported rolls 90. Since the edge of the supporting plate 11 and the plate supporting board 30 are fixed by a plate edge fixing mechanism, the wobbling of the roll supporting tool 10 during conveyance is prevented.
