Abstract
A rotating electric machine has a brush holder that holds brushes. A first cover through which a rotor shaft passes is provided on one end side in an axial direction. A brush holder accommodating portion that accommodates the brush holder is recessed in the first cover in the axial direction from an outer side of the first cover. The brush holder is disposed in the brush holder accommodating portion such that a distance between a lower surface of the brush holder and an inner peripheral wall of the brush holder accommodating portion is larger than a distance between another portion of the brush holder and another inner peripheral wall of the brush holder accommodating portion.
