と共に、一端が該給気導入室に接続され、他端が
上記各第２隙間内に指向した複数の給気孔を形成
したことを特徴とする気体軸受装置。 In a gas bearing device in which the rotating shaft is suspended and supported by gas in a gap formed between the rotating shaft and the bearing, an annular ring is formed on either the outer circumferential surface of the rotating shaft or the inner circumferential surface of the bearing. A large diameter portion is formed, and a first gap with a small cross-sectional area is formed between the outer circumferential surface of the large diameter portion and the inner circumferential surface of the bearing. A second gap having a large predetermined cross-sectional area is formed, and an air supply introduction chamber is formed in the wall of the bearing, one end of which is connected to the air supply introduction chamber, and the other end of which is connected to each of the second gaps. A gas bearing device characterized by forming a plurality of oriented air supply holes.
