<P>PROBLEM TO BE SOLVED: To provide a foil bearing having a bearing surface whose flexibility can be easily adjusted. <P>SOLUTION: The foil bearing includes a cylindrical external member 1, a shaft 2 inserted into the inner periphery of the external member 1, and a plurality of leaves 3 interposed between an inner peripheral face 1b of the external member 1 and an outer peripheral face 2a of the shaft 2, and each having one end mounted on the external member 1. On the inner peripheral face of each leaf 3, the bearing surface 3d is provided which forms a wedge-shaped radial bearing clearance. On each leaf 3, a protrusion 2b is provided in contact with the inner peripheral face 1b of the external member 1 at a position apart from the fixed end of the leaf 3. The side closer to the free end than the protrusion 2b of each leaf 3 is brought into contact with the free end of the other leaf 3. <P>COPYRIGHT: (C)2012,JPO&INPIT |
