Abstract: An airfoil journal bearing including a bearing housing having an inner surface forming a hollow so that a rotation shaft is insertable in the hollow; an airfoil in 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 enclosing an outer surface of the bearing housing. The bearing housing includes an insert slit formed through the bearing housing from the inner surface of the bearing housing to the outer surface of the bearing housing. The airfoil includes an insert part bent from a circumferential direction of the airfoil to a radial direction of the bearing housing and extending, through the insert slit, to the outer surface of the bearing housing. The airfoil is engaged with an outer surface of the ring member through the insert part.
