A belt conveyor comprising an endless, fixed-width belt mounted on a pulley provided on rollers. Protrusions are formed on the back surface of the endless, fixed-width belt, and each of the protrusions has a shape comprising inwardly curved front and rear sides and tapering towards its tip end, and the pulley that is detachably mounted to each of the rollers is formed with holes, and each of the holes has a shape that fits each of the protrusions of the belt. The protrusions of the belt snugly engage with holes of the pulley, thus preventing meandering of the rotating belt.
