Abstract: PURPOSE: To improve a vibration removing or vibration controlling effect and to miniaturize an apparatus. CONSTITUTION: The dead weight of an object to be supported OB is supported by the pressure of an internal gas in a first gas chamber 69 via a holding member 62. An adjuster 74 adjusts the position of the holding member in the direction of gravity by driving a movable apparatus 149 for varying a content capacity in the first gas chamber by varying a content capacity in a second gas chamber. Thus, when the holding member is displaced in the direction of the gravity caused by vibration, etc, the movable apparatus is driven by the adjustor to keep the holding apparatus at its original position. Furthermore, the movable device is prevented from contacting with the object to be supported, so that this never directly deforms the object to be supported. By only driving the object by the variation of the content capacity in both of the gas chamber, there is not problem even when the gas in the first gas chamber is rigid.
