Abstract
To obtain a rotating electric machine capable of suppressing vibrations generated at the time of driving and achieving downsizing. The rotating electric machine includes: a rotor; a stator including a stator core provided on an outer side with respect to the rotor in a radial direction of the rotor; a motor frame, which includes a tubular portion provided on an outer side with respect to the stator core in the radial direction, and has the stator fixed thereto; and an intermediate member, which is provided on an outer peripheral surface of the stator core in the radial direction, and is held in a state of being press-fitted to an inner peripheral surface of the tubular portion in the radial direction, wherein a stiffness of the intermediate member per unit length is higher than a stiffness of the tubular portion per unit length.
