ABSTRACT:
A shaft with a gear and a small-diameter drum mounted and a different shaft with a gear and a large-diameter drum mounted are axially mounted in a rotatable condition across the inside of a housing. The gears are engaged with each other. A case has a horizontally long cavity part being open to one side, and rope insertion holes. The cavity part has, in a movable condition, an adjusting tool between an energizing means and a restricting means. The adjusting tool has a rope insertion hole. The rope is wound around the small-diameter drum and the large-diameter drum respectively in the same direction. The externally let-off rope obtained through an upper rope let-off hole has, at an upper end, a hook. The externally let-off rope obtained through a lower rope let-off hole is in a hanging-down condition resulting from insertion of the rope into the above rope insertion holes.
