Abstract
A housing, a top foil including a bearing surface that faces the rotary member, and a bump foil placed between the top foil and the housing are provided. The bump foil is configured to elastically support the top foil by expanding in a rotation direction. When a load received by the bearing surface from the rotary member is less than or equal to a threshold value, the bump foil supports the top foil with a gap formed between the bump foil and the housing and with a gap formed between the bump foil and the top foil. When the load received by the bearing surface from the rotary member exceeds the threshold value, the top foil and the bump foil locally form a plain bearing to support the rotary member.
