Abstract
The objective is to prevent the flange of a ring member for holding the stator core from enlarging the diameter of a rotating electric machine and to eliminate a screwing space and a pedestal portion in the housing case so as to suppress the weight of the rotating electric machine from increasing; one end of the ring member for holding the stator core protrudes from the outer circumference of the stator core toward the rotation axle and the ring member is fixed to the cover or the housing case at the protruding portion.
