A supporting device ( 300 ) for supporting a guide rail ( 200 ) for guiding a movable member subjected to relative displacement in relation to the base table ( 3 ). The supporting device includes, base bodies ( 410, 510 ) engaged onto the base table ( 3 ) and carrying the guide rail ( 200 ), and holding section ( 440, 530 ) for holding the guide rail ( 200 ) intervening between the guide rail ( 200 ) in the state where the guide rail is carried by the base bodies ( 410, 510 ). The holding section ( 440, 530 ) supports the guide rail ( 200 ) in the state where it can move swingingly. A change in the posture or position of the base bodies ( 410, 510 ) is offset with a swinging movement by the holding section, and does not affect the guide rail. As a result, excessive force is not applied on the guide rail, so that the form of the guide rail is maintained.
