An ascender includes a pulley, an input shaft, a support member, a transmission mechanism, a rope guide, a cam, an energizing member, an operating member, and a closing member. A rope is removably wound on the pulley. An output shaft of a rotary electric tool is removably connected to the input shaft. The transmission mechanism transmit a rotational force of the input shaft to the pulley. The cam moves toward the pulley to bite into the rope so as to prevent a movement of the rope when the rope is going to move in a descending direction. The cam moves away from the pulley to allow the movement of the rope when the rope is going to move in an ascending direction.
