Abstract
Provided is an air foil thrust bearing including a bump foil plate in which a plurality of bump foils are formed and an arrest ring protrudes in a thickness direction; and a top foil plate in which a plurality of top foils are formed, a through-hole penetrating through both sides of a second plate is formed in a position corresponding to the arrest ring, the top foil plate being stacked on the bump foil plate, wherein the arrest ring is inserted into and penetrates through the through-hole, the arrest ring is bent toward the top foil plate so that the second plate is caught in the arrest ring, and a time for a thrust runner to rise from the top foil at an early stage of starting a rotor as the arrest ring is spaced apart from the second plate.
