A hermetic type compressor including balance weights installed on a rotor so as to compensate for rotating unbalance of a rotary shaft, thereby reducing a level of noise. The hermetic type compressor has a compressing unit, which compresses a refrigerant, a driving unit, which provides driving force to compress the refrigerant, a stator, a rotor that rotates in electromagnetic interaction with the stator, and a rotary shaft, which is press-fit into a center of the rotor so as to transmit the driving force of the driving unit to the compressing unit, and has an eccentric part on one end thereof. The rotor has balance weights so as to compensate for rotating unbalance of the rotary shaft caused by the eccentric part on upper and lower ends thereof, where each balance weight has a shape of a ring, part of which has at least a hollow space.
