A reciprocating compressor includes a driving unit ( 16 ) having an outer stator ( 26 ) and an inner stator disposed at a predetermined air gap there between, and a moving member positioned between the outer stator ( 26 ) and the inner stator ( 28 ) and linearly and reciprocally moved; a compression unit ( 18 ) having a cylinder ( 38 ) fixed at an inner circumferential surface of the inner stator ( 28 ) and a piston ( 22 ) linearly moved in the cylinder ( 38 ) by being connected to the moving member, a support portion ( 20 ) supporting the compression unit ( 18 ) and the driving unit ( 16 ); and a resonant spring unit positioned ( 24 ) at a rear portion of the driving unit ( 16 ), disposed at the support portion ( 20 ), and inducing a resonant movement of the piston ( 22 ). Therefore, a resonant spring ( 62,64 ) of the compressor can be moved horizontally and straight forwardly by reducing a torsion moment of the resonant spring ( 62,64 ), a width of the compressor can be reduced, and a concentricity of a driving unit ( 16 ) and a compression unit can be maintained.
