PROBLEM TO BE SOLVED: To provide a novel structure by which a static fluid bearing can easily manufactured and constituted with high precision. SOLUTION: A bearing body 200 of the static pressure bearing comprises a first bearing member 210 integrally having a first rugged end 211, and a second bearing member 220 integrally having a second rugged end 221 fittable in the axial direction with respect to the first rugged end. The first bearing member and the second bearing member are fitted in the axial direction in such a manner that the first rugged end and the second rugged end are combined with each other. A plurality of recessed groove 221g extending radially and communicating with a bearing gap G are radially formed at least at one of a first bearing side 211t and a second bearing side 221t. The first bearing side and the second bearing side abut on each other so that a plurality of throttles P are dispersed around an axis by a recessed groove. COPYRIGHT: (C)2009,JPO&INPIT
