<p>The present invention relates to a radial foil bearing (3) for supporting a rotary shaft (1). The radial foil bearing includes a top foil (10), a back foil (11), and a bearing housing (12) accommodating the top and back foils. The top foil (10) is formed by winding a rectangular metal foil into a cylindrical shape so that one end (10b) of the metal foil is extended out in a tangential direction of a cylinder (10a) formed by the metal foil. An engagement groove (13) is formed on an inner circumferential surface of the bearing housing in an axial direction of the bearing housing, and the engagement groove (13) is formed so that a depth direction thereof corresponds to one tangential direction of the cylinder (10a) of the top foil (10). The one end (10b) of the top foil (10) engages with the engagement groove (13).</p> |
