Abstract
A weight supporting apparatus supports the weight of a structure required to have very high surface precision, without affecting the surface precision of the structure. The weight support apparatus includes a driving unit for moving a driven body in the direction of gravity with respect to a base, and a supporting unit for supporting the weight of the driven body at a position after being driven, wherein the driving unit and supporting unit are so arranged that the drive force of the driving unit and the support force of the supporting unit are on the same axis.
