PROBLEM TO BE SOLVED: To solve the problem of becoming difficult for providing a highly efficient and excellently reliable compressor since a shaft inclines in a clearance range of a journal bearing and is in a state of end tooth bearing at both ends of the journal bearing, and an oil film is easily cut. SOLUTION: An annular slit groove and an outer diameter thin part are constituted in an end part of a journal bearing part, and rigidities of both ends of the journal bearing is reduced, and when the shaft is in a state of end tooth bearing, since the bearing is deformed along the shaft, the end tooth bearing is relieved. |
