軸受。 A plurality of elastic foils having foils corresponding to the circumferential surface of the shaft are fixedly installed on the inner circumferential surface of the bearing housing so that the tips of the foils on both sides overlap each other on both sides of the circumferential direction of the fixed installation part on the bearing housing. A foil journal bearing characterized in that it also includes a foil-like elastic support that elastically supports the overlapping portion of the foil with respect to the bearing housing and sets a contact force of the foil with respect to the shaft.
