A cage is rescued by a rescue operation controller in an elevator. The rescue operation controller evaluates a rescue operation voltage value in the rescue operation of the cage and applies voltage of the rescue operation voltage value to a brake coil according to a signal from a speed detector. The rescue operation voltage value is a value of the voltage needed to reduce braking force of a brake device and move the cage by means of imbalance between the cage and a counterbalance.
