Abstract: A reciprocating compressor comprises an inside stator formed by piling a plurality of stator cores to have an actinomorphic cylinder shape, which is press-fitted to a frame, and a streak protection member and a burr shielding ring installed between the inner aspect of the inside stator and corresponding outer aspect of the frame. Thereby the burr generating between the frame and the inner stator by a streak is prevented previously, and even if a burr is generated, this burr is locked in a burr escape unit in the burr-shielding ring. Therefore degrading of valve function and an abrasion of a sliding unit in a compressing unit by the burr generating is prevented and the vibration noise of the compressor is reduced by assembling the frame and the inside stator strongly.
