Abstract
An apparatus for moving a table or a stage having movable parts adapted to be guided by guide rail means slidingly and rectilinearly. At least the movable parts are made of a non-iron light metal material. The sliding surfaces of the movable parts making sliding contact with the guide rail means are made of a self-lubricating material, while the sliding surfaces of the guide rail means making sliding contact with the movable parts are made of a material having a higher hardness and wear resistance than the non-iron light metal material, so that the weight of at least the movable parts is reduced to decrease the weight of the apparatus as a whole.
