    Abstract: The present invention relates to an air foil journal bearing including a bump foil having a plurality of elastic bumps and provided and coupled inside a bearing housing, a mid-foil provided inside the bump foil, formed in a circumferential direction, and having at least one circumferential end coupled to the bearing housing, and a top foil provided inside the mid-foil, formed in the circumferential direction, and having at least one circumferential end coupled to the bearing housing, in which a stepped portion is formed as a radius of an inner peripheral surface of a partial circumferential region of the mid-foil is smaller than a radius of an inner peripheral surface of the remaining region, such that an additional pressure is generated in a section in which a maximum positive pressure is applied when a rotor rotates at low speed, such that the rotor may float at a relatively low rotational speed, and friction and vibration between the rotor and the top foil may be reduced.
