ABSTRACT:
An on-vehicle rotary electric machine, such as AC generator, is provided. The machine comprises a rotary shaft, a pole core, plural magnetic poles, plural permanent magnets, and plural holding members. The magnetic poles are located at intervals in a circumferential direction and passing magnetic flux between two mutually-adjacent of the magnetic poles. Each permanent magnet intervenes between the two magnetic poles and is magnetized to reduce leakage of the magnetic flux to be passed. Each holding member holds each permanent magnet between the two magnetic poles. Each holding member is secured on the two magnetic poles and has a first plate portion enclosing a radially outer surface of each permanent magnet and two second plate portions enclosing side surfaces of each permanent magnet. The two second plate portions are rigidly coupled to the first plate portion and are lower in rigidity than the first plate portion.
