Abstract
A reciprocating compressor provided with a damper is disclosed. The compressor includes a fastening member that fastens a stator and a cylinder block. The fastening member may be named a stator bolt. The compressor further includes a damper. The damper is press-fitted into and coupled to an insertion portion of the fastening member protruding from an upper surface of the cylinder block. Through this, the damper may protect a compressor body from external impact by avoiding a drive motor and a compression unit, which are the compressor body, from directly colliding with a housing due to a vibration generated during the operation of the compressor.
