Abstract
A foil bearing includes a foil holder and a plurality of foils fixed to the foil holder and arrayed in a circumferential direction. Each of the foils includes a top foil portion having a bearing surface, an extending portion formed on one circumferential side of the top foil portion, an underfoil portion formed on another circumferential side of the top foil portion, and an insertion slot formed between the top foil portion and the underfoil portion in the circumferential direction. The insertion slot includes a positioning portion and a wide portion that is larger in circumferential width than the positioning portion and is opened to an end portion of each of the foils. An edge of the top foil portion, which is opposed to the wide portion, retreats toward the one circumferential side with respect to an edge opposed to the positioning portion.
