Rotary compressor and refrigeration cycle device

A rotary compressor comprising:

• a shaft rotatable around a central axis;
• a plurality of compression mechanism units including a first compression mechanism unit, a second compression mechanism unit, and a third compression mechanism unit disposed to be aligned from one side to the other side in a central axis direction of the shaft;
• a plurality of eccentric parts provided on the shaft and including a first eccentric part, a second eccentric part, and a third eccentric part corresponding to the first compression mechanism unit, the second compression mechanism unit, and the third compression mechanism unit;
• a first balancer rotating together with the shaft;
• and
• a second balancer disposed on the other side of the first balancer and rotating together with the shaft, wherein
• angles between a direction of eccentricity of the first balancer with respect to the central axis of the shaft and directions of eccentricity of the plurality of eccentric parts with respect to the central axis of the shaft are configured to increase in an order of the third eccentric part, the second eccentric part, and the first eccentric part, and
• angles between a direction of eccentricity of the second balancer with respect to the central axis of the shaft and directions of eccentricity of the plurality of eccentric parts with respect to the central axis of the shaft are configured to increase in an order of the first eccentric part, the second eccentric part, and the third eccentric part.
