In an abrasion preventive structure of a reciprocating compressor, by forming a coating layer made of Ni&#x2014;P alloy material having high hardness onto the surface of a frame at which front () and rear () resonance springs are contacted or spring mounting grooves () of a spring supporting rod () or spring fixation protrusions or the inner circumference of a cylinder built-in type frame, although each resonance spring () is rotated while repeating compression/relaxation, it is possible to prevent abrasion of the spring mounting grooves () or the spring fixation protrusions, and accordingly reliability of the compressor can be improved.
