Abstract
In an elevator apparatus, a safety device that makes a car perform emergency stopping is mounted to the car. A rope is installed in a loop inside a hoistway. The rope is connected to the car. A tensioning sheave around which the rope is wound is disposed in a lower portion of the hoistway. A tensioning sheave displacement detecting portion detects downward displacement of the tensioning sheave that accompanies dropping of the car due to breakage of the suspending body and activates the safety device.
