PROBLEM TO BE SOLVED: To solve the problem in which: when a belt is deviated in an axial direction of rollers to abut against a flange, an end of the belt is applied with a large load; after the abutment of the belt against the flange, when the belt runs while the end of the belt abuts against the flange, the end continues to be applied with the load; and the load thus applied causes cracks in the end of the belt, which results in damage to the belt.SOLUTION: A belt 3 is laid over a plurality of rollers, and runs in association with the rotation of the rollers. A belt controller controls the movement of the belt 3 in the axial direction of the rollers. At least one roller 52 of the plurality of rollers has, on at least one end thereof, a belt abutting part 7 against which an end of the belt abuts; and the belt abutting part is flexible. |
