Zusammenfassung:A thrust foil bearing (3) of the present disclosure includes a base plate (30) which includes an insertion hole (30a) through which a rotation shaft (1) is inserted, a back foil (20) which is disposed around the insertion hole (30a) and supported by the base plate (30), and a top foil (10) which is supported by the back foil (20), wherein the top foil (10) includes an expansion portion (13) in which a width of the expansion portion in a virtual straight line direction in which a virtual straight line extends decreases in a direction orthogonal to the virtual straight line, the virtual straight line being supported by the back foil (10) on a most downstream side in a rotation direction of the shaft.
