PROBLEM TO BE SOLVED: To solve the problem in which: when a belt deviates to an axial direction of a roller and abuts against a flange at a belt abutting part, a large amount of load is applied to an end of the belt, and when the belt runs with the end thereof contacting with the flange after the abutment against the flange, the end continues to be applied with the load from the flange; and accordingly, cracks are caused in the end of the belt due to the load applied to the end of the belt from the flange, which results in damage to the belt.SOLUTION: A roller has a belt abutting part against which an end of a belt abuts at at least outside of one end in an axial direction of the roller. The belt abutting part has a cone that increases in diameter toward the outside in the axial direction, and the shortest distance from the inner circumference in the axial direction of the cone to the axis of the cone is shorter than a radius of the one roller. |
