A linear compressor comprising:
- a cylinder;
- a piston configured to reciprocate inside the cylinder, the piston comprising a sliding portion and a head portion;
- a supporter comprising a plate disposed at a side of the piston opposite to the head portion of the piston;
- an elastic body disposed at the piston and having an outer side coupled to an inner circumferential surface of the piston;
- and
- a rod extending axially and having (i) a first side coupled to a central area of the elastic body and (ii) a second side connected to a central area of the plate,
- wherein the first side of the rod is formed of a male thread,
- wherein a coupling hole formed of a female thread is comprised in the central area of the elastic body,
- wherein the coupling hole is screw-coupled to the first side of the rod,
- wherein an outer circumferential surface of the elastic body is formed of a male thread,
- wherein a part of an inner circumferential surface of the piston to which the elastic body is coupled is formed of a female thread,
- wherein the elastic body is screw-coupled to the inner circumferential surface of the piston, and
- wherein the elastic body comprises a plurality of first flow holes disposed about an axis of the rod.
