A hermetic motor-driven compressor is capable of decreasing both the resonance sound due to an oil feed pipe and the resonance sound due to a crankshaft generated when the oil feed pipe is rotated while being dipped in the refrigerating machine oil. Within a hermetically sealed enclosure, a compression component and a motor drive component are supported through an elastic support arrangement, and the compression component comprises a crankshaft adapted to be rotatively driven by the motor drive component through an eccentric portion and provided with a journal, a balance weight disposed at the eccentric portion and a coaxial oil feed pipe disposed in the balance weight so as to revolve coaxially with the journal, so that the stirring of the refrigerating machine oil can be suppressed.
