PROBLEM TO BE SOLVED: To provide an elevator emergency stop device for preventing excessive deceleration due to a change of inertial force applied to a car with the number of passengers in the car and the length of a broken rope. SOLUTION: The device comprises a deceleration detecting weight 51 suspended from the rope 52 installed on the elevator car 100 and arranged movable up and down, and a wedge body 61 for sliding via a sliding part a guide rail 1 to be served as a guide member when the car 100 is moved. The inertial force on the deceleration detecting weight 51 reduces the thrust of the sliding part of the wedge body 61 on the guide rail 1 to keep the deceleration of the car constant.
