Abstract
In an elevator apparatus, a brake device stops a car from running. The brake device has a brake control portion for controlling a braking force generated at a time of emergency braking to adjust a deceleration of the car, and a timer circuit for invalidating the control of the braking force performed by the brake control portion after a lapse of a predetermined time from a moment when an emergency braking command is generated.
