    Abstract: A thrust foil bearing includes: a base plate including an insertion hole through which a shaft is inserted; and a top foil disposed around the insertion hole, wherein the top foil includes: a slit dividing the top foil into an inner area and an outer area in a radial direction of the insertion hole; a sandwiched part disposed in the outer area; an extending part extending from the sandwiched part to the inner area; and an inclined part being in the inner area, having an end on one side in a circumferential direction of the insertion hole connected to the extending part, extending from the extending part toward another side in the circumferential direction, and inclined with respect to a flat surface of the base plate extending a direction orthogonal to an axial direction of the insertion hole.

    Abstract: A slide bearing which can be manufactured at low cost is provided. The slide bearing (1) is provided with a cylindrical bearing main body (2) into which a shaft member is inserted, and an elastic ring (3) for urging the bearing main body (2) diametrically inward, the elastic ring (3) being mounted to the bearing main body (2). The bearing main body (2) has a sliding surface (21) which slides against the outer peripheral surface of the inserted shaft member, a plurality of first slits (25) running along the direction of an axis O from one end surface (23) toward another end surface (24), a plurality of second slits (26) running along the direction of the axis O from the other end surface (24) toward the one end surface (23), a plurality of first elastic ring interlocking parts (27) protruding diametrically outward at one end part (220) of the outer peripheral surface (22), and a plurality of second elastic ring interlocking parts (28) protruding diametrically outward at another end part (221) of the outer peripheral surface (22). The first elastic ring interlocking parts (27) and the second elastic ring interlocking parts (28) are positioned so as not to overlap each other seen in an imaginary plane P perpendicular to the axis O.
