PURPOSE:To prevent a riding cage from its transverse vibration due to bending of a guide rail by providing an anti-unbalanced load generating device, which reduces an unbalanced load generated in a guide device, in the riding cage. CONSTITUTION:A riding cage 2 is positioned by placing its hanging center 0 to a side of a balance weight 10 relating to a center of gravity position W. As a result, the riding cage 2 is tumbled in a direction A of a gate 2a. A guide device 6 supports an unbalanced load, caused by tumbling this riding cage 2, to guide the riding cage 2. Here, the riding cage 2 is guided by the guide device 6 in a condition that a guide load, acting on a side surface of a guide rail in a vertical direction to a surface of a pair of the guide rails 4 through a guide piece, is deviated to the one side surface of the guide rail. In the guide devices 6 mounted to upper and lower parts of the riding cage 2, anti-unbalanced load generating devices, formed of electromagnets 14 for attracting the guide rail 4 in a direction of reducing an unbalanced component of the guide load, are provided. |
