It is a curved surface.

Claims

[Claims for Utility Model Registration] (1) A rotary shaft of a rotary compressor that is supported in bearing holes of bearing plates provided at both ends of the cylinder and that rotates a roller within the cylinder; A groove is formed in the outer peripheral wall with a predetermined width of the base material surface left on both ends of the outer peripheral wall in a predetermined area of the rotating shaft to be arranged, and a wear-resistant layer made of ceramic is provided in the groove. The rotating shaft of the rotary compressor is a feature. (2) The rotating shaft of a rotary compressor according to claim (1), wherein the wear-resistant layer is formed on the same surface as the remaining base material surface. (3) The rotating shaft of a rotary compressor according to claim (1), wherein the rotary shaft of the rotary compressor is tapered at a predetermined slope from the end of the groove to the bottom of the groove. (4) The rotating shaft of a rotary compressor according to claim (3), wherein the intersection of the taper and the groove bottom is a curved surface with a predetermined curvature.
