An apparatus for supplying lubricating oil of a reciprocating compressor is provided to realize smooth pumping operation of a lubricating oil piston by reducing friction between lubricating oil springs and a lubricating oil cylinder, thereby improving oil supply performance. A lubricating oil piston(112) is slidably inserted into a lubricating oil cylinder(111) for pumping lubricating oil of a casing(10) inside while performing relative motion with a frame. A plurality of lubricating oil springs(113,114) elastically support both sides of the lubricating oil piston for supplying the elasticity to the lubricating oil piston. Spring fixing parts(112a) are formed at both sides of the lubricating oil piston for fixing ends of the lubricating oil springs so that the lubricating oil springs maintain the original place.
