[0003] The inclination between the axis of the rotating shaft and the axis of the bearing greatly affects the reliability of the bearing portion. If the inclination exceeds an allowable value, the life of the bearing is significantly reduced. Also, when the inclination of the rotating shaft increases due to misalignment between the main bearing shaft center and the sub-bearing shaft center,
The orbiting scroll and the fixed scroll may come into contact with each other. Therefore, the axes of the main bearing and the sub-bearing must be accurately matched. In a conventional assembling method, after a stator and a frame are fastened to a casing, a main bearing, a rotating shaft and a rotor are assembled. Then, in order to accurately match the axis of the main bearing and the sub-bearing, a plurality of thin plates are inserted into the gap between the stator and the rotor to position the rotary shaft with respect to the stator, and the cylindrical pin as the centering member is set in the The rotary shaft and the sub-bearing are positioned by being inserted into a through hole of the bearing portion and an oil supply hole of the rotary shaft.

In the conventional assembling method,
When inserting a thin plate into the gap between the stator and the rotor, the positioning accuracy of the rotating shaft improves as the thickness of the thin plate is increased and the gap between the stator, the thin plate and the rotor is reduced, but workability when inserting and removing the thin plate is improved. When the thickness is reduced in consideration of workability, there is a problem that the positioning accuracy of the rotating shaft is deteriorated.
