Abstract:
A foil bearing ( 40 ) includes foils ( 42 ) at a plurality of portions in a rotation direction of a shaft member ( 11 ). A top foil portion (Tf) including a bearing surface (S 2 ) is formed in a region including a front end ( 421 ) of each of the foils ( 42 ), and a back foil portion (Bf) is formed in a region including a rear end ( 422 ) of each of the foils ( 42 ). A gap (C 1 ) is secured between, of two of the foils adjacent to the foil ( 42 ) in a rotation direction (R) and a direction opposite to the rotation direction, the rear end ( 422 ) of the foil on the rotation direction side and the front end ( 421 ) of the foil on the side opposite to the rotation direction side. A width of the gap (C 1 ) is set to be non-uniform in a direction (N) orthogonal to the rotation direction.

Claim (Index 1):
A foil bearing, comprising foils which are arranged at a plurality of portions in a rotation direction of a shaft member to be supported,\n the foils each having a front end located on the rotation direction side and a rear end located on a side opposite to the rotation direction side, the foils each forming a top foil portion comprising a bearing surface in a region including the front end of the foil and a back foil portion, which is arranged behind the top foil portion of adjacent one of the foils, in a region including the rear end of the foil, wherein a gap in the rotation direction is secured between, of two of the foils adjacent to any one of the foils in the rotation direction and the direction opposite to the rotation direction, the rear end of the foil on the rotation direction side and the front end of the foil on the side opposite to the rotation direction side, and wherein a width of the gap is set to be non-uniform in a direction orthogonal to the rotation direction.
