In an elevator device, a drive unit has a drive sheave, a motor for rotating the drive sheave, and a motor driving portion for driving the motor. The motor driving portion is controlled by a control unit. When a car is running, the control unit monitors a load on at least one component within the drive unit, and generates a control command regarding a running speed of the car in accordance with a state of the load, and outputs the control command to the motor driving portion.
