きる。In particular, the spiral ridge 14 extends from the vertical surface B side to the ends 12a, 12b from the base 14a to the outer peripheral surface 13.
Since the sheet material or the like is inclined to the side, the sheet material or the like is less likely to be caught in the spiral groove 15 when the sheet material or the like is tensioned to both ends, and the spiral ridge 14 is easily inclined to the end portions 12a and 12b due to its elasticity. For this reason, it is possible to prevent the edge of the sheet material or the like from being cut into the groove and to be damaged, and to further enhance the effect of extending or preventing wrinkles. Therefore, even when a thin film material having low elasticity is fed, the quality can be improved without causing distortion or damage.
