Abstract
A fluid machine includes a plurality of fluid dynamic plain bearings supporting a rotating member. The fluid dynamic plain bearings each include: a top foil; a bump foil; and a bearing housing. The top foil has a bearing surface that has one end portion and the other end portion in a circumferential direction of the bearing surface. The top foil has a fixed end and a free end respectively formed at the one end portion and the other end portion. A movement of the free end in an axial direction of the rotating member is regulated by a regulating member. A clearance through which a fluid flows is formed between the fixed end and the free end. The free end has a discharge passage through which a foreign substance contained in the fluid is discharged from the clearance. The discharge passage is formed through the free end.
