PROBLEM TO BE SOLVED: To improve assembling performance of rollers arranged in a pair above and below a carrying path. SOLUTION: A backup roller 50 is attached, by putting a bearing 112 attached to a rotary shaft 110, into a cut 118 formed at a supporting part 106 of a pair of brackets 100. A brush roller 48 is mounted on the backup roller by putting the bearing 128 of the rotary shaft 124 into the cut 144 of the bracket 138, making a coupling 134 of the rotary shaft 126 face a receiving part 152 of a receiving member 150 attached to the bracket 146 and fitting a connection member 156 of a driving shaft 152 to a connection hole 136. At this time, since an interval of the supporting parts 142 and 148 of the bracket receiving the brush roller is wider than the interval of the supporting parts 106 supporting the backup roller, assembly is facilitated. |
