Abstract
The present invention relates to an airfoil bearing installation structure in which a spacer is provided on a bent portion of a foil assembly, the spacer has catching pieces having elasticity, and catching projections are formed on an inner wall surface of a slot formed in a housing so that the catching pieces are caught by the catching projections. Therefore, it is possible to prevent an axial movement and separation of the foil assembly without additionally installing a separate component for blocking an inlet of the slot.
