Beschreibung
Zusammenfassung:	An emergency stop device for an elevator car, including: a link configured to be rotated about a rotary shaft installed on a car by movement of a speed governor rope; a rail stopper provided to one end of the link; a roller guide mounted to the car; and an elastic member provided between another end of the link and the car. The elastic member causes a spring reaction force to be reduced to bring the rail stopper into abutment against the roller guide even when the rail stopper is displaced by the link, when the displacement exceeds a preset threshold value due to further displacement by the link along with the movement of the speed governor rope at a time of occurrence of rope breakage.
