摘要： The present invention relates to an oil-retaining bearing for a rotary machine. In the oil-retaining bearing for a rotary machine according to the present invention, a first lock section is provided in a bearing housing; a first thrust spacer is relatively rotatably mounted in the vicinity of the end face of the oil-retaining bearing for a rotary machine; the first thrust spacer is provided with a second lock section, in engagement with the first lock section; a second thrust spacer is relatively non-rotatably mounted on the rotating shaft; and a third thrust spacer having elasticity is relatively rotatably mounted on the rotating shaft; the third thrust spacer being interposed between the first thrust spacer and the second thrust spacer. Furthermore, in the oil-retaining bearing structure for a rotary machine according to the present invention, a small hole is provided in the bearing housing through which the rotating shaft is mounted; at least one axial groove is formed in the inner surface of the bearing housing; and at least one radial groove is formed in the inner surface of the bearing housing; the axial groove being connected with the small hole section through the radial groove.
