摘要： A radial foil bearing includes: a cylindrical top foil disposed so as to face a rotary shaft; a back foil disposed outside in the radial direction of the top foil; and a cylindrical bearing housing accommodating the top foil and the back foil. The bearing housing is provided with a limiting member which limits movement of the back foil. A locking recess is provided in a central part in the axial direction of an inner circumferential surface of the bearing housing. In addition, the limiting member includes a locking protrusion and is fixed to the bearing housing by the locking protrusion being locked into the locking recess.
