In an electric rotary machine, a stator, a metallic supporting member
configured to support the stator, and a rotor are provided, the rotor is
relatively rotatably supported with respect to the stator, a magnetic
path is formed via a gap portion between the stator and the rotor to give
a torque to the rotor, and a space section is provided to interrupt the
magnetic path at a position of the metallic supporting member near to a
magnetic pole of the stator facing the gap portion.
