Abstract
An elevator apparatus provided with a guiding device for guiding a passenger cage without vibration with respect to the guide rails. Sensors are provided so that a pressure applied to the guiding device from the guide rails is maintained constant, and an actuator is driven by an output of the sensor. The sensor may be a pressure sensor and, as the output of the sensor increases, the distance between the guide rail and the passenger cage is controlled in a manner so as to be decreased. The guiding device immediately follows the bend of the guide rail and an unbalanced load of the passenger cage so that transversal vibration of the passenger cage is considerably reduced.
