To provide a method which enables an internal space of a rolling bearing to be observed more accurately regardless of components.SOLUTION: When an internal space of a rolling bearing 1 filled with grease G is observed, a thermosetting resin is flowed into the internal space S of the rolling bearing 1 after the rolling bearing 1 is operated for a predetermined time to be cured. Then, the rolling bearing 1 is cut to observe the internal space S.SELECTED DRAWING: Figure 1 【課題】構成部材によらずに、転がり軸受の内部空間内をより正確に観察できる方法を提供する。【解決手段】グリースＧを充填した転がり軸受１の内部空間を観察するにあたり、所定時間運転後の転がり軸受１の内部空間Ｓに熱硬化性樹脂を流し込み、硬化させた後、転がり軸受１を切断して内部空間Ｓを観察する。【選択図】図１
