Zusammenfassung:	To provide a radial foil bearing that can readily acquire a desired performance and improves assemblability.SOLUTION: A radial foil bearing 1 includes: a top foil 2 surrounding a periphery of a shaft and facing the shaft in a radial direction; a bump foil 3 disposed in a radial outside of the top foil 2; and a cylindrical housing 4 disposed in a radial outside of the bump foil 3 and accommodating the top foil 2 and the bump foil 3. The bump foil 3 is pressed onto an inner peripheral surface 4a of the housing 4 by magnetic force.SELECTED DRAWING: Figure 2 【課題】所望の性能を容易に得ることができ、組み立て性を向上できるラジアルフォイル軸受を提供する。【解決手段】ラジアルフォイル軸受１は、シャフトの周囲を取り囲み、シャフトと径方向で対向するトップフォイル２と、トップフォイル２の径方向外側に配置されるバンプフォイル３と、バンプフォイル３の径方向外側に配置され、トップフォイル２及びバンプフォイル３を収容する筒状のハウジング４と、を備える。バンプフォイル３は、磁力によってハウジング４の内周面４ａに押圧されている。【選択図】図２
