A reciprocating compressor comprises a casing including a suction pipe (SP) through which a fluid is introduced from the outside and a discharge pipe (DP) through which the fluid is discharged outside and forming a predetermined internal space; a compressor main body ( 700 ) positioned in the casing ( 100 ), compressing the fluid introduced through the suction pipe (SP) with a linear reciprocating motion of a piston ( 420 ) and discharging the compressed fluid through the discharge pipe (DP); and a supporting unit ( 600 ) including a plurality of coil springs connecting the compressor main body ( 700 ) to the casing ( 100 ), wherein the plurality of coil springs ( 610, 620 ) includes, respectively, end coils ( 590 ) tightly wound so as to be fixed to one surface of the compressor main body ( 700 ) and to one surface of the casing ( 100 ) and an inner coil ( 580 ) having at least one part which is tightly wound and positioned between the end coils ( 590 ), thereby minimizing the lateral vibration of the compressor, which is generated in a direction that a reciprocating motor is operated in operation of the reciprocating compressor.
