Claims

[Scope of utility model registration request]

In a foil bearing in which a metal thin film consisting of one leaf or a combination of multiple leaves is used as a bearing member and the rotating shaft is supported in the radial or axial direction by a gas film formed between the foil bearing and the rotating shaft, the back surface of the metal thin film is A foil bearing characterized in that a vibration absorbing layer made of a lubricant or a viscoelastic material is attached to the foil bearing.
