PROBLEM TO BE SOLVED: To securely suppress the swaying of a tail cord even when it severely sways due to earthquake or wind and prevent it from coming out of a hoistway duct. SOLUTION: A hitch 5 is provided projecting from an elevator car 3 through a clearance 8 of the hoistway duct 7, and the tail cord 6 is suspended from the hitch within the hoistway duct. In this state, a cord stopper member 11 is installed across the clearance of the hoistway duct, on one side of the duct through a rotation fulcrum 12, and a weight 13 weighing as required is suspended on the rear end side of the cord stopper member. Normally, the cord stopper member can prevent the tail cord from coming out of the clearance due to swaying since the cord stopper member maintains its horizontal position over the hoistway duct clearance by means of the gravity of the weight, and when the car passes the cord stopper member, the car can travel without being affected by the cord stopper member since the hitch pushes the cord stopper member against the gravity of the weight, allowing the cord stopper member to rotate and let the hitch pass through it.
