Claims

[Scope of utility model registration request]

A motor is disposed in the upper part of the sealed case, and a compression device for compressing refrigerant as the motor rotates is disposed in the lower part, and the rotation axis of the rotor of the motor is formed in the upper and lower parts of the compression device. In a rotary compressor that is rotatably supported by first and second bearings, the rotating shaft of the rotor projects upward, and the motor is fixed to an inner wall of a sealed case or fixed above the motor. A third bearing consisting of a ring-shaped bearing bracket fixed to the child and a bearing fixed to the same bearing bracket is provided, and the protruding rotating shaft is rotatably supported by the third bearing. A rotary compressor, wherein the bearing bracket has a hole diameter equal to or larger than the inner diameter of the stator.
