In an elevator apparatus, an abnormal acceleration detecting mechanism includes a mass body that operates in connection with movement of the car, the abnormal acceleration detecting mechanism operating a safety device using a force of inertia that is generated by the mass body if an acceleration that exceeds a predetermined set value arises in a car. A breakage detecting means detects breakage of a suspending means that suspends the car. A resistance force applying apparatus applies a resistance force to a mechanism for activating the safety device such that the resistance force is applied when breakage of the suspending means is not detected by the breakage detecting means and the resistance force is reduced if breakage of the suspending means is detected by the breakage detecting means. |
