PURPOSE: An oil feed structure for linear compressor is provided, in which discharge valve and suction valve are fed with sufficient amount of oil, to thereby prevent wear of valve and improve compression performance. CONSTITUTION: A linear compressor includes a cylinder(20) having a compression space; a piston(40) reciprocating in the compression space(P) of the cylinder by the driving force transmitted from a motor(M); a discharge valve(61) for opening/shutting the compression space of the cylinder; a suction valve(63) coupled to the piston, and which opens/shuts the refrigerant flow channel(F) formed inside of the piston, so as to allow the refrigerant gas to be sucked into the compression chamber of the cylinder through the refrigerant flow channel; an oil pocket(42) formed to have predetermined depth and width at the outer periphery of the cylinder. The cylinder has an oil passage hole(22) for allowing oil to flow into the oil pocket. The piston has an oil passage hole(43) for allowing the oil introduced into the oil pocket of the piston to flow into the refrigerant flow channel formed inside of the piston.
