Abstract
The foil bearing includes a housing, a top foil, and bump foils. The bump foil includes first support portions that contact an outer circumferential surface of the top foil, second support portions that contact an inner circumferential surface of the housing, and coupling portions that couple the first support portions and the second support portions together such that the first support portions and the second support portions are disposed alternately in a rotation direction of a rotating body. When a load input from the rotating body increases, the bump foil is deformed to increase one of the number of the first support portions that contact the outer circumferential surface of the top foil and the number of the second support portions that contact the inner circumferential surface of the housing before increasing the other one of the numbers.
