PURPOSE: A structure is provided to reduce noise while allowing the length and strength of spring to be changed using a screw. CONSTITUTION: A structure comprises a spring(60) for supporting a fixture unit(50) of a compressor and buffering a vibration and impact, wherein the spring has at an interior thereof a screw(70) for controlling the length of the spring in accordance with a resonance avoidance and mass change with respect to the fixture unit of the compressor. The spring has at a front end thereof a cap(61) having an insertion hole(61a) for an insertion of the screw, and at a rear end thereof a spring seat(62) having a constriction hole(62a) for constricting the screw. Thus, the strength of the spring can be suitably changed, to thereby suppress noise increase.
