摘要： PROBLEM TO BE SOLVED: To increase a load carrying capacity and bearing rigidity of a bearing without increasing the size of the bearing and the pressure of a fluid externally supplied, in a journal bearing type sliding bearing having a hydrostatic bearing structure that supports rotational motion of a shaft by externally supplying a high-pressure fluid to a gap between the outer periphery of the shaft and the inner periphery of a substantially cylindrical bearing.SOLUTION: The sliding bearing comprises: a substantially cylindrical sleeve the inner periphery of which slides via a fluid on a rotatable shaft outer periphery; a hydrostatic pressure supply passage penetrating the sleeve and supplying a high-pressure fluid from an external pressure source into the inner periphery of the sleeve; and a hydrostatic pressure pocket which has a recessed shape in a radial direction on the inner periphery of the sleeve, and where the hydrostatic pressure supply passage is open via an orifice. At least one row of hydrostatic pressure pockets where a plurality of hydrostatic pressure pockets are circumferentially arranged, is formed in the vicinity of each of both ends of the sleeve inner periphery in the axial direction of the shaft. A cylindrical inner peripheral region having no hydrostatic pressure pocket is formed in the center part of the sleeve, while being interposed by the hydrostatic pressure pocket rows, with a broader width in the shaft axial direction than the sum of widths of the hydrostatic pressure pocket rows.
