受。A rotating shaft having an air supply hole in the center and a flange at the end is inserted into a through hole of the member, and the pressurized gas supplied through the air supply hole is released to the outer peripheral surface of the rotating shaft and both sides of the flange. In a shaft-fed type static pressure gas bearing in which the rotary shaft is statically supported in the radial direction and the thrust direction by a member, the above-mentioned support has a central part of the outer end surface of the above-mentioned flange and a side plate opposite thereto. A pump-in type dynamic pressure generation groove is formed on either side of the flange, and the hydrostatic bearing area on the inner end surface of the flange is adjusted so that the supporting force in the thrust direction is equal on both sides of the flange. A shaft-supplied static pressure gas bearing characterized in that the area of the static pressure bearing is larger than that of the outer end surface.
