徴とする空気軸受。A plurality of bearing element members each including a thin plate piece having bending rigidity and a holder that supports the thin plate piece in a cantilever manner are arranged at regular intervals along the inner peripheral surface of the bearing box, and the holders are fixed to the bearing box. In addition, in the air bearing in which the free end of the thin plate piece extends toward the rotational direction of the rotating shaft, a leaf spring is provided at the free end of the thin plate piece, and the leaf spring is connected to the adjacent leaf spring on the rotational direction side. An air bearing characterized in that an extending portion of a thin plate piece is brought into elastic contact, and vibration of the thin plate piece is damped by the elastic contact.
