Claim 15:
16. An airfoil journal bearing comprising:
a bearing housing having an inner surface forming a hollow through the bearing housing so that a rotation shaft is insertable in the hollow and so that, when the rotation shaft is inserted in the hollow, an axial direction of the airfoil journal bearing is the same as a longitudinal direction of the rotation shaft and the hollow longitudinally extends in the axial direction;
an airfoil in the hollow and extending in a circumferential direction of the hollow so that, when the rotation shaft is inserted in the hollow, the airfoil encloses at least 180 to 360 degrees of a circumference of the rotation shaft and the airfoil receives pressure generated by rotation of the rotation shaft; and
a ring member connected to the bearing housing and enclosing an outer surface of the bearing housing in a circumferential direction of the bearing housing, and configured to fix a position of the airfoil in the axial direction, wherein
the bearing housing, based on a cross-section perpendicular to the axial direction, comprises an insert slit formed through the bearing housing from the inner surface of the bearing housing forming the hollow to the outer surface of the bearing housing, and
at least some of the airfoil passes through the insert slit and is engaged with the ring member.
