Claims

[Scope of utility model registration request]

On the compression mechanism part of the rotary compressor body,
A pair of lower cylinders are formed, and a pair of upper and lower crank parts are provided on the rotating shaft of the electric motor, with the upper crank part having a roller in the upper cylinder, and the lower crank part having a roller in the lower cylinder. A rotary compressor in which the upper cylinder and the lower cylinder are respectively fitted, wherein an intermediate thrust receiving part is provided in which the upper crank part is brought close to a partition plate that partitions the upper cylinder and the lower cylinder.
