A rotating shaft lifting jig is inserted between a rotating shaft of a rotary machine and a bearing stand surrounding the outer periphery of at least a lower part of the rotating shaft. The jig for lifting the rotating shaft includes: a pedestal which is supported on an inner peripheral surface of the bearing stand; and a jack part which is disposed between the pedestal and the outer peripheral surface of the rotating shaft and extends/contracts in the radial direction. The radial dimension of the pedestal is smaller than a radial clearance between the rotating shaft and the bearing stand. A rotor receiver having a cylindrical surface conforming to the outer peripheral surface of the rotating shaft is provided between the jack part and the rotating shaft. The rotor receiver is provided with a plurality of support members in directions different from the direction of the jack part.
