In an elevator tension pulley device, a guide plate is fixed to a guide rail via a support arm, and a tension pulley moves while being guided in a vertical direction as a main shaft inserted into an elongated hole in the guide plate moves vertically through the elongated hole. As a result, the number of components of the elevator tension pulley device can be reduced, and the elevator tension pulley device can be installed in a hoistway easily.
