The roller includes an inner circle, an outer circle, and an inflatable cushion arranged between the inner circle and the outer circle with the volume thereof changing as air charge inflated thereinto changes. by adjusting the air charge of the inflatable cushion, the outer diameter of the roller is increased as the air charge inflated into the inflatable cushion increases, at the same time, the conveyor surrounding the exterior of the roller is tightened to increase the tension degree of the conveyor without disassembling other mechanisms of the conveying device, which is simply operated to be capable of saving labors and time.
