Claim 0:
1. 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
a ring member that is annular and is connected to the bearing housing, and enclosing an outer surface of the bearing housing in a circumferential direction of the bearing housing, wherein
the bearing housing comprises:
based on a cross-section perpendicular to the axial direction, an insert slit formed through the bearing housing in a radial direction of the bearing housing from the inner surface of the bearing housing forming the hollow to the outer surface of the bearing housing, and

the airfoil comprises:
based on a cross-section perpendicular to the axial direction, an insert part bent from a circumferential direction of the airfoil to the radial direction of the bearing housing and extending, through the insert slit, to the outer surface of the bearing housing,

wherein the airfoil is engaged with an outer surface of the ring member through the insert part.
