PROBLEM TO BE SOLVED: To recycle and reuse a motor-driven element by reducing deterioration of an organic material such as insulating paper and a winding used in the motor-driven element, even if a hermetic compressor is structured so that a compression element and the motor-driven element are placed in an enclosure and the inside of its enclosure is exposed to coolant and oil under a high temperature and a high pressure. SOLUTION: A compression element 6 is placed in an enclosure 1, a motor- driven element 2 is completely separated from the enclosure 1 and the power of the motor-driven element 2 is transmitted to the compression element 6 with the intervention of a dome-shaped cap 15 of a non-magnetic material forming the enclosure 1 by using the first magnet 14 of a power transmitting coupling and the second magnet 16 of the power transmitting coupling. The motor-driven element 2 is not exposed to coolant and oil under a high temperature and a high pressure by this structure. Thereby, deterioration of an organic material such as insulating paper and a winding used in the motor-driven element 2 is substantially reduced.
