べり軸受装置。Measures the pressure of pressure oil in a sliding bearing device that supports the rotating shaft of a rotating machine and has a lift-up mechanism that supplies pressure oil from the outside to the underside of the rotating shaft to form an oil film when the rotating machine is stopped or at low rotation speeds. and a comparator that compares the measured pressure change pattern with a pressure change pattern during normal lift-up that has been previously measured and stored in a storage device. a second comparator comprising a flow rate measuring device that measures the flow rate of the supplied pressure oil, and a comparator that compares the measured flow rate with the flow rate during normal lift-up that has been measured in advance and stored in the storage device. At least one of the lift-up monitoring devices is provided, and a control circuit is provided to stop the starting operation of the starting device of the rotating machine in response to an output signal determined to be abnormal from the lift-up monitoring device. A sliding bearing device characterized by:
