るロータリコンプレツサ。 A cylinder block having a cylindrical cylinder chamber, a main bearing and a sub-bearing attached to both sides of the cylinder block, a roller fitted to an eccentric portion of a rotating shaft in the cylinder chamber, and the cylinder. A compression element, which includes a blade provided in a blade groove formed in the block and abutting against the outer circumferential surface of the roller to partition the cylinder chamber into a low pressure chamber and a high pressure chamber, is placed in a sealed case with lubricating oil stored at the bottom. In the rotary compressor, the rotary compressor is arranged such that the refrigerant compressed by the compression element is discharged through the internal space of the sealed case, and at least one of the main bearing and the sub-bearing is provided with a side surface of the blade on the low pressure chamber side. A rotary compressor characterized in that a notch is formed at a position facing a sliding portion between the blade groove and the blade groove.
