When the rotor shaft rotates, an isothermal compression process, an equivalent heating process and an isothermal expansion process are sequentially performed. The rotor shaft includes a compressor rotor(2), a regenerator rotor(5) and an expander rotor(7), which are coupled to the rotor shaft. The compressor is provided at an inside thereof with the compressor rotor, which is offset from an internal surface of the compressor. The compressor rotor includes a plurality of vane slots(8) into which vanes(9) are inserted.
