In an elevator apparatus, a safety device is activated using a force that is generated by a mass body that includes sheaves and a rope, if acceleration of a car reaches an abnormal acceleration set value. A tensioning sheave that can be moved vertically in order to apply tension to the rope is included among the sheaves. A vertical vibration suppressing apparatus that is connected to the tensioning sheave allows vertical displacement of the tensioning sheave during normal operation while also suppressing vertical vibration of the tensioning sheave if the acceleration of the car reaches the abnormal acceleration set value. |
