PROBLEM TO BE SOLVED: To provide a quad foil journal air bearing where uniformity of stiffness within the bearing is substantially improved.SOLUTION: A quad foil journal air bearing (5) includes a journal sleeve having an inner circumference that defines an inner surface. A first foil assembly (11a) includes a first key coupled to the inner surface of the journal sleeve. The quad foil journal air bearing further includes a second foil assembly (11b) having a second key coupled to the inner surface of the journal sleeve.SELECTED DRAWING: Figure 1B 【課題】軸受内の剛性の均一性を大幅に高めた４層フォイル空気ジャーナル軸受を提供する。【解決手段】４層フォイルジャーナル空気軸受（５）は、内側表面を画定する内周面を有するジャーナルスリーブを含む。第１フォイルアセンブリ（１１ａ）は、ジャーナルスリーブの内側表面に接続される第１キーを含む。４層フォイルジャーナル空気軸受は更に、ジャーナルスリーブの内側表面に接続される第２キーを有する第２フォイルアセンブリ（１１ｂ）を含む。【選択図】図１Ｂ
