It is possible to reduce as much as possible the displacement that occurs between the slide base of the linear guide device and the movable body mounted on it, especially the influence of the track rail mounting accuracy on the motion of the slide base.
It is possible to configure a straight line guide device that is easy to install the track rails and absorbs even a slight misalignment of the track rails to guide the movable body in a straight line lightly. Further, if the track rail has misalignment, it is unavoidable that the circulating condition of the balls incorporated in the slide table deteriorates and some vibration noise is generated, but if the movable body mounting plate of the present invention is used, In addition to damping the vibration sound, it is possible to prevent the vibration sound from resonating and expanding.
