In addition, when an abnormal load is applied to the guide rail during an earthquake or the like, the bracket is elastically deformed and the guide rail is displaced in the horizontal direction. However, the horizontal displacement of the base side of the guide rail at this time is prevented by the concave edge of the over-displacement prevention body. As a result, excessive displacement of the guide rail due to the action of the abnormal load is limited within the elastic deformation range of the bracket, so that the bracket is not plastically deformed when the abnormal load is applied. Therefore, the rigidity of the bracket is reduced to suppress vibration propagation, and the living room adjacent to the hoistway during the operation of the elevator can be quieted, and the displacement range when an abnormal load acts on the guide rail does not cause plastic deformation of the bracket. The position is suppressed, and an abnormal displacement of the guide rail can be dealt with, so that there is an effect that the effect of reducing the propagation of vibration during operation can be realized without any trouble.

Further, when an abnormal load is applied to the guide rails during an earthquake or the like, abnormal displacement of the guide rails in the horizontal direction is prevented by the recessed edge of the over-displacement prevention body via the eye plate. Thus, the overdisplacement of the guide rail is suppressed within the elastic deformation range of the bracket, so that the rigidity of the bracket is reduced to suppress the propagation of vibration, and there is an effect that the living room can be calmed without any trouble during operation.

Further, as described above, the present invention is provided with a vibration damping element between the recess of the over-displacement preventing body and the base side of the guide rail formed by the eye plate.

Accordingly, when the vibration caused by the operation of the driving device propagates through the guide rail and the bracket to the living room, the rigidity of the bracket is reduced to suppress the propagation of the vibration. Further, when an abnormal load is applied to the guide rails during an earthquake or the like, abnormal displacement of the guide rails in the horizontal direction is prevented by the recessed edge of the over-displacement prevention body via the eye plate. Thus, the overdisplacement of the guide rail is suppressed within the elastic deformation range of the bracket, so that the rigidity of the bracket is reduced to suppress the propagation of vibration, and there is an effect that the living room can be calmed without any trouble during operation. In addition, since the collision with the over-displacement prevention body due to the abnormal displacement of the guide rail is buffered by the damping element, the collision sound with the over-displacement prevention body at the time of the abnormal displacement of the guide rail is reduced, so that there is an effect of silence.

Further, as described above, the present invention is provided with the over-displacement preventing member provided on the bracket and integrally formed with the bracket.
