ABSTRACT:
An elevator apparatus includes guide devices having guide members engaged with a pair of guide rails so as to guide a car along the guide rails in a manner to hold the car in a proper position. Each of the guide devices includes a resilient support member having a small spring constant supporting the guide member in such a manner that the guide member is movable in a direction perpendicular to a plane of the guide rail. An axis of suspension of the car is deviated from a position of a center of gravity of the car so as to cause a guide load, acting on a side surface of the guide rail via the guide member in a direction perpendicular to the plane of the guide rail, to have a deflected load acting on the guide rail in one direction. The guide device further includes an anti-deflected load generating device for generating an anti-deflected load in a direction to reduce a deflected load component of the guide load produced by the above deviation. With this arrangement, a lateral vibration of the car, which would be caused by an inherent bending of the guide rail, or a bending of the guide rail due to an error in installation of the guide rail or aging, is prevented.
