In the rotating electric machine, the pulley, the front bearing, and the field core are arranged in a stated order from the one end side of the rotary shaft toward another end side of the rotary shaft. The pulley is fastened to the rotary shaft with use of a male thread formed on the one end side of the rotary shaft and a nut to be mounted to the male thread. The rotary shaft has a flange portion, which projects radially outward, and is arranged to a position between the front bearing and the field core in an axial direction of the rotary shaft.
