A vertical dual pulley is provided to allow the two pulleys to rotate in respective horizontal and vertical directions and to prevent separation of a cable from the pulleys. A vertical dual pulley comprises a first pulley(10), a second pulley(20), and a fixing plate(30). The first pulley guides a cable in the horizontal direction. The second pulley guides a cable in the vertical direction. The fixing plate is hinged by bolts to the first and second pulleys. The first and second pulleys have peripheral grooves on their central parts so that a cable is settled on the grooves. |
