摘要： A stage system includes a movable stage, a guide mechanism for guiding the stage with respect to a predetermined direction, and a preloading mechanism for producing a magnetic attraction force with which the rigidity of the guide mechanism can be increased, wherein a portion to be attracted by the magnetic attraction force is made of a material having a product of a residual magnetic flux density Br and a holding force Hc in a hysteresis curve, not greater than 100 J/m3, this being very effective to reduce the hysteresis force, which is resistance due to the residual magnetic force, as compared with the preloading attraction force, whereby high precision positioning of the stage is accomplished.
