A piston support structure of a reciprocating compressor is provided. In the piston support structure, including a piston receiving linear reciprocating driving power generated by a reciprocating motor and being in a linear reciprocating motion in a compression space formed in a cylinder and a first resonant spring and a second resonant spring positioned on both sides of the piston, the first resonant spring and the second resonant spring for elastically supporting the linear reciprocating motion of the piston, the spring constant of the second resonant spring opposite to the first resonant spring is larger than the spring constant of the first resonant spring positioned on the side of the compression space of the cylinder. In the process of the piston being in the linear reciprocating motion between the top dead center and the bottom dead center of the compression space formed in the cylinder, the stress concentration of the second resonant springs for elastically supporting the piston is reduced. Accordingly, it is possible to prevent the endurance of the second resonant springs from deteriorating due to the fatigue of the second resonant springs. Therefore, it is possible to extend the durability of the resonant springs.
