ことを特徴とするフオイル・ジヤーナル軸受。 The shaft is supported by an elastic foil installed in the housing of the bearing, and the shaft is supported in a floating manner by the pressure increase in the wedge-shaped space between the peripheral surface of the shaft and the surface of the foil when the shaft rotates. In a journal bearing, a plurality of elastic foils corresponding to the periphery of a shaft are set to such a length that they do not overlap each other and are installed in a cantilevered manner in the bearing housing, and a midpoint of each of these elastic foils is defined as described above. A foil journal bearing comprising a plurality of flat elastic supports that elastically support an elastic foil from outside within a bearing housing.
