Abstract: A linear compressor includes a cylinder that defines a compressor space and that is configured to compress refrigerant in the compressor space, a piston located in the cylinder and configured to perform a reciprocating motion in an axial direction relative to the cylinder, a mover coupled to the piston and configured to transmit a driving force to the piston to cause the piston to perform the reciprocating motion, a stator that defines a cylinder space that receives the cylinder, in which the stator is configured to generate the driving force together with the mover, and a supporting unit that includes an overlap portion that covers at least a portion of the stator, that is coupled to the stator, and that contacts the stator.
