Provided is an elevator device including a main rope configured to support a car and a counterweight, a hoisting machine configured to be driven with the main rope wound therearound, a hoisting-machine controller configured to control the hoisting machine, a car brake controller configured to control a car brake device configured to apply a load to car rails to control raising and lowering of the car, and a vibration detection device configured to detect vibration of the car. When the vibration of the car is detected based on an output signal from the vibration detection device under a running state in which the hoisting-machine controller controls drive of the hoisting machine, the car brake controller controls the car brake device to generate a braking force until the vibration becomes smaller than a set value.
