Abstract:
1. An on-vehicle rotary electric machine, comprising: a rotary shaft driven to rotate, the shaft having a longitudinal axis defining an axial direction, radii defining a radial direction, and a circumference defining a circumferential direction; a pole core secured on the rotary shaft; a plurality of magnetic poles formed as parts of the pole core, the magnetic poles being located at intervals in the circumferential direction, passing magnetic flux between two mutually-adjacent magnetic poles, and each having an axial inner surface directed inward in the axial direction; a plurality of permanent magnets each intervening between the two mutually-adjacent magnetic poles, each magnet being magnetized to reduce leakage of the magnetic flux to be passed; and a plurality of holding members each holding therein each permanent magnet between the two mutually-adjacent magnetic poles, each holding member being formed as a rectangular box-shaped hollow frame member and being secured between the two mutually-adjacent magnetic poles and each holding member having:
