PROBLEM TO BE SOLVED: To accomplish a constitution that assembling of a guide roll relative to a holder is easy and the guide roll is not dropped off from the holder after the holder is attached to a mounting surface by a simple constitution. SOLUTION: The holder 70 having a base plate 71, a pair of bearing plates 72 and an enlargement prevention plate 73 is constituted by bending one sheet of metal sheet of a predetermined developed shape. A distal end side of the bearing plate 72 is pushed/enlarged relative to the holer 70 before it is attached to a sheet guide surface 68, small diameter parts 82 at both ends of the guide roll 80 are engaged with respective penetration holes 72a from an inner side respectively. Thereafter, by engaging an upper hook 71a and a lower hook 71b with the sheet guide surface 68, the holder 70 is attached to the seat guide surface 68. Relative to the force for enlarging the distal end side of the bearing plate 72, the enlargement prevention plate 73 is abutted on the sheet guide surface to prevent enlargement.
