A conveyer having a width controller is provided to actively drive the width controller by preventing rust or foreign matters, such as a lubricant and cleaning solution, from covering the width controller, to uniformly make a width of a conveyer plate, and to improve production efficiency and elongate the longevity of the width controller. A conveyer comprises a transferring device moving subject matters; conveyer plates(21, 22) installed at both sides of the transferring device to support the both sides of the subject matters and guide; and a width controller composed of wires(31) connected with each of the conveyer plates, a wire driving pulley(32) operating a wire(31a), and a slave pulley(33) connected by the other wire(31b). In addition, the width controller comprises a middle pulley(34) installed between the wire driving pulley and the slave pulley. The middle pulley is composed of a first groove coiled by the wire connected with the wire driving pulley; a second groove coiled by the other wire connected with the slave pulley; a first middle pulley coiled by the wire connected with the wire driving pulley; and a second middle pulley coiled by the wire connected with the slave driving pulley and installed on the same shaft with the first middle pulley.
