Patent ID: 6838801

Claim:
A rectifying structure comprising: a stator; an electrode segment disposed in the stator; a rotor; a commutator segment disposed in the rotor; and a rotating element made of a conductor disposed between the stator and the electrode segment, and the rotor and the commutator segment, the rotating element rolling on toward the stator, the electrode segment, the rotor, and the commutator segment, so that the rotor is so supported as to be rotatable about the stator, and the electrode segment is electrically connected to the commutator segment; wherein the stator includes an electrode-segment forming member; the electrode segment is disposed in the electrode-segment forming member; an annular stator-side groove is disposed in the electrode-segment forming member and the electrode segment; the rotor includes a commutator-segment forming member; the commutator segment is disposed in the commutator-segment forming member; an annular rotor-side groove is formed in the commutator-segment forming member and the commutator segment so as to face the stator-side groove; and the rotating element is disposed within the stator-side groove and the rotor-side groove.
