<p>In a substrate stage device (PST), an X movable element (56), which faces an X stator (82) provided on an X beam (25) and in which a magnetic attractive force is generated with respect to a weight canceling device (50), is fixed at the tip of an arm (54) of the weight canceling device (50). The weight canceling device (50) transfers its own weight and part of the weight of a micro-movement stage (30) that the weight canceling device (50) supports to a floor (11) via a base frame (14) by means of the magnetic attractive force. Therefore, the biased load applied to a vibration prevention device (34) is reduced.</p> |
