Abstract
A load of a workpiece, which is applied to a slider (68), is supported by guide blocks (78) and guide rails (30a, 30b) provided for a frame (12). On the other hand, pin members (72), which constitute a floating mechanism (64) provided under the slider (68), are slidably engaged with fitting members (66) installed to recesses (62) of a projection (54). Therefore, a ball screw (16) is prevented from any application of the load of the workpiece via a displacement member (46).
