Abstract:
Provided are a rotary compressor and a refrigeration cycle device equipped with the rotary compressor. The rotary compressor is equipped with: a primary bearing and a secondary bearing which are arranged above and below a cylinder; and an end bearing which is located at the motor section-side end of the rotating shaft, and the rotary compressor is configured so that the rotational balance when the rotating shaft rotates is maintained. A solid lubricating agent is applied to the sliding surfaces between the rotating shaft and primary and secondary bearings. The gap between the rotating shaft and the primary and secondary bearings when the solid lubricating agent is applied is set to be less than the gap between the rotating shaft and the end bearing, and the gap between the rotating shaft and the primary and secondary bearings when the solid lubricating agent is not applied is set to be greater than the gap between the rotating shaft and the end bearing.
