The present invention relates to a timing pulley and a belt, and more specifically, to a timing pulley and a belt, which can be controlled in a stable way also in a device requiring a precise figure control such as a CNC and a semiconductor producing machine by preventing a distance between the belt and the pulley when the belt and the pulley operate or stop by coming in contact with each other to prevent a slip and a backlash. To this end, the present invention comprises a pulley and a belt connected to the pulley. A first gear tooth and a second gear tooth are formed on the outer circumference surface of the pulley, and a third gear tooth and a fourth gear tooth corresponding to the first gear tooth and the second gear tooth are formed on the belt. The first gear tooth and the second gear tooth are formed on both sides of the center of the outer circumferential surface of the pulley in the shape of ′V′. The third gear tooth and the fourth gear tooth are formed on both sides of the center of the belt in the shape of ′V′. |
