ABSTRACT:
A device, which is provided at a car, for guiding the car along guide rails, the device comprises, a non-contact type of actuator configured to generate a magnetic force which keeps the actuator away from surfaces of a rail by predetermined distances, a unit configured to detect a distance between the rail and the car, a unit configured to determine an amount of displacement of the rail which is caused by a load which generates at time of guiding, based on a value of the magnetic force and the distance, a unit configured to acquire position information regarding the car, a unit configured to calculate an amount of a warp occurring at time of setting the rail, which corresponds to the information, and a unit configured to control the magnetic force based on a total value of the determined amount of the displacement and the amount of the warp.
