Abstract
In an elevator apparatus, a brake device is controlled by a brake control device. The brake control device is capable of performing braking force reduction control for reducing the braking force of the brake device at a time of emergency braking of a car. The brake control device monitors a running state of the car at the time of emergency braking thereof, and makes a switchover between validity and invalidity of braking force reduction control such that the car is stopped within a preset allowable stopping distance.
