Claims

[Scope of utility model registration request]

One of the piston ring groove and the piston ring provided in the piston that reciprocates in the cylinder has a convex portion that prevents rotation of the piston ring in the circumferential direction, and the other has the convex portion. A reciprocating compressor, characterized in that it has a recess into which a reciprocating compressor is fitted.
