There is obtained an elevator apparatus which can adapt to changes in the distance between guide rails and improves the ride comfort and safety of an elevator car and improves also the ease with which the guide rails are installed. The elevator apparatus is equipped with a car which ascends and descends in an elevator shaft, a pair of guide rails which are provided in the elevator shaft and whose mutual distance changes partially, a car guide device which is provided in the car, can freely move forward and backward to any horizontal position with respect to the car, and constantly abuts against the guide rails by responding to changes in the mutual distance of the guide rails, and a safety gear device which is provided in the car, can freely move forward and backward to any horizontal position with respect to the car, is constantly opposed to the guide rails with equal spacing therefrom by responding to changes in the mutual distance of the guide rails, and brings the car to an emergency stop by grasping the guide rails during a fall of the car at an overspeed.
