Abstract
A hydrostatic guide device includes: a fixed member having vertical guide faces; a movable member having vertical slide faces; a fluid supply device; a hydrostatic pocket to which a first fluid pressure based on a dimension of a gap is applied, and that urges the movable member with a first urging force; and a hydraulic pocket to which a second fluid pressure based on a dimension of a gap is applied, and that urges the movable member with a second urging force. A variation of the second fluid pressure is smaller than a variation of the first fluid pressure. When the first urging force and the second urging force are balanced with each other in a horizontal direction, the gap between the vertical guide face and the vertical slide face becomes a set value.
