An elevator has a power outage operation function including an emergency stop device that is provided in the elevator car, and a drive mechanism that is configured to drive the emergency stop device. An electric actuator is configured to actuate the drive mechanism, and a control device is configured to control an operation of the car. The electric actuator includes a movable element mechanically connected to the drive mechanism, electromagnets facing the element, and a mechanism to convert rotation of a motor into linear movement of the electromagnets. When the control device determines that the electric actuator is actuated due to a power outage, the control device instructs the electric actuator to perform a return operation of returning the movable element to a standby position, and operates the car to move up and land on a nearest floor above a stop position of the car when the return operation fails.
