Claims

[Scope of utility model registration request]

A housing that defines the outside of the compressor has an electric motor section in an upper inner part and a compressor part in a lower part, and the crankshaft of the compressor part is provided eccentrically from the rotation axis of the electric motor part. In a rotary compressor having blades that divide a cylinder chamber into a suction chamber and a compression chamber, the above-mentioned rotary compressor is located within a range of 0° to 90° from the eccentric direction of the crankshaft to the rotational direction of the crankshaft with the rotational axis as the center. A first balance weight is provided on the lower end surface of the rotor of the electric motor, and a second balance weight is provided on the upper end surface of the rotor at a rotational angular position of 180 degrees from the rotational angular position of the first balance weight. rotary compressor.
