Beschreibung
Zusammenfassung:	A thrust foil bearing (3) includes a base plate (30) including an insertion hole (30a) through which a rotating shaft is inserted and a support surface (31) disposed around the insertion hole (30a) on one side of the insertion hole (30a) in an axial direction, and a back foil (20) disposed on the support surface (31), in which the support surface (31) has a plurality of inclined surfaces (31a to 31d) of which inclination angles inclined toward the other side of the base plate (30) in the axial direction become shallower in order toward an outside of the insertion hole (30a) in a radial direction, and the back foil (20) is divided into a plurality of divided regions (25) in the radial direction by a slit (24), and the plurality of divided regions (25) are supported by the plurality of inclined surfaces (31a to 31d).
