This radial foil bearing (3) is provided with a cylindrical top foil (10) arranged facing a rotating shaft (1), a back foil (11) arranged on the radially outer side of the top foil, and a cylindrical bearing housing (12) for accommodating the top foil and the back foil. Regulating tools (30, 40) for regulating the movement of the back foil are provided to the bearing housing. An interlocking concavity (21) is formed in the axial-direction center of the inner peripheral surface of the bearing housing. The regulating tools have interlocking convexities (32, 42), and these interlocking convexities interlock with the interlocking concavity, whereby the regulating tools are secured to the bearing housing. |
