Claims

[Scope of utility model registration request]

Storing an electric element and a compression element in a sealed container,
The rotor that constitutes this electric element is formed by injecting molten metal from the axial direction during die casting so that sprue marks remain on the end face of the end ring, and the compression element is formed on the end face of the end ring of the rotor where the sprue marks remain. The hermetic compressor is equipped with a balance weight to balance the unbalanced force of the hermetic compressor, characterized in that the balance weight has a recess on the end surface of the end ring into which a sprue is fitted. balance device.
