SOLUTION: This rotating electric machine 19 includes a stator 12 wound by a winding wire and a rotor 14 having magnets 22, 24 of which different polarities are alternately located in a circumferential direction.

When current flowing through the winding wire is at a predetermined value or more, the magnet 24 is rotated so that the deviation in the circumferential direction between the polarity of the magnet 24 and the same polarity of the magnet 22 adjacent to each other in the axial direction becomes relatively smaller against energizing force by the spring 16.
