ABSTRACT:
A hermetic compressor is disposed with an annular motor stator, a motor rotor, a casing and plural spot joining portions. The motor rotor is disposed such that it may freely rotate in a space inside the motor stator. The casing includes a cylindrical portion. The cylindrical portion houses the motor stator and the motor rotor. The plural spot joining portions fix the motor stator to the cylindrical portion by spot joining in a state where a clearance is secured between the motor stator and the cylindrical portion.
