Abstract
In an elevator apparatus, a brake device is controlled by a brake control device. The brake control device has a first brake control portion for operating the brake device to stop a car as an emergency measure upon detection of an abnormality, and a second brake control portion for reducing a braking force of the brake device when a deceleration of the car becomes equal to or larger than a predetermined value during emergency braking operation of the first brake control portion. The second brake control portion controls the brake device independently of the first brake control portion.
