The radial foil bearing (3, 40, 50) includes: a top foil (9) disposed facing a rotary shaft (1); an intermediate foil (10, 41) disposed outside of the top foil (9) in the radial direction thereof; a back foil (11) disposed outside of the intermediate foil (10, 41) in the radial direction; and a cylindrical bearing housing (12, 42, 51) accommodating the top foil (9), the intermediate foil (10, 41) and the back foil (11). Engagement recesses (31, 35) are formed on both side surfaces of the bearing housing (12, 42, 51) so as to be opposite to each other. The intermediate foil (10, 41) includes intermediate foil pieces (10a, 41a) disposed in the circumferential direction of the bearing housing (12, 42, 51). An engagement-projecting piece (10b, 41b) engaging with the engagement recess (31, 35) is formed in each intermediate foil piece (10a, 41a). |
