PURPOSE: A piston coupling structure for reciprocating compressor is provided to reduce cost, parts count and manufacturing procedures by reducing the number of bolts for coupling the magnet frame and piston. CONSTITUTION: A piston coupling structure comprises a connection portion(111) having a plurality of stopper holes(111a), and which is formed at an end of a magnet frame(110A) which constitutes a mover of a reciprocating motor; and a fixing portion(121) having a plurality of stopper protrusions(121a), and which is formed at an end of a piston(120) to be coupled with the magnet frame. The stopper protrusions are engaged with the stopper holes formed at the magnet frame. Alternatively, the magnet frame has a connection portion with a plurality of stopper protrusions, and the piston has a fixing portion to be engaged with the stopper protrusions of the magnet frame.
