The radial foil bearing (3) is provided with a top foil (10), a back foil (11), and a bearing housing (12) which houses the top foil (10) and the back foil (11). A through-groove (13) is formed in the inner peripheral surface of the bearing housing (12), and engagement grooves (20) are formed in the through-groove (13) by a stationary member (16). |
