Abstract
By adopting a construction in which a first balance weight is provided at the side end portion of the eccentric shaft portion of the auxiliary shaft portion and a second balance weight is provided at the side end portion of the eccentric shaft portion of the main shaft portion, it becomes possible to provide sufficient first balance weight and second balance weight, without spoiling the compact size of the compressor, thus enabling the reduction of noise and vibrations.
