Claims

[Claims for Utility Model Registration] (1) An electric element and a compression element are provided in a closed container, and an oil supply hole is provided along the rotation axis of the compression element driven by the electric element, and the eccentricity of the rotation axis is provided. In a rotary compressor, a rotary compressor is provided with a small oil supply hole that communicates with the oil supply hole and extends in the radial direction, the communication hole that communicates with the oil supply hole is opened in the end face of the stepped eccentric part, and the rotation shaft A rotary compressor characterized by facing a bearing. (2) The rotary compressor according to claim (1) of the utility model registration, wherein the communication hole is opened only on one end surface of the eccentric portion of the rotating shaft. (3) The rotary compressor according to claim 1, wherein the communication hole is opened at both end faces of the eccentric portion of the rotating shaft.
