A hydrostatically supporting device for slide wherein a first slide member is provided with four guide surfaces constituting a square guide bore, and a second slide member having a square cross section is mated with the first slide member for sliding movements therebetween. Each of guide surfaces is provided with a pair of hydrostatic supporting surfaces formed at longitudinal ends of the guide surfaces, respectively, and each hydrostatic supporting surface is formed with a first hydrostatic pressure pocket formed at lateral center of the hydrostatic supporting surface and extending in the sliding direction. This first hydrostatic pressure pocket is provided with an oil supplying nozzle for supplying pressurized oil therethrough. Further, the hydrostatic supporting surface is provided with a pair of second hydrostatic pressure pockets each formed at opposite lateral ends of the hydrostatic supporting surface and extending in the sliding direction, and a pair of connecting grooves formed between the first and second hydrostatic pressure pockets for introducing the oil to the second hydrostatic pressure pockets.
