Patent ID: 6853112

Claim:
A rotating electric machine for a vehicle, comprising: a shaft; pole cores including a plurality of claw-like magnetic poles formed on an outer periphery thereof, the claw-like magnetic poles being disposed to engage with each other and to rotate integrally with the shaft; a plurality of permanent magnets each of which is disposed between circumferentially adjacent two claw-like magnetic poles and each of which is magnetized in a direction where magnetic flux leakage is reduced between the circumferentially adjacent two claw-like magnetic poles; and a magnet holder for holding each of the permanent magnets, the magnet holder being fitted between side surfaces of the circumferentially adjacent two claw-like magnetic poles, the magnet holder including a radial outer surface, and a protrusion that radially protrudes from the radial outside surface to approximately a center portion between circumferentially adjacent two claw-like magnetic poles, wherein: each of the claw-like magnetic poles has a flange portion extending in a circumferential direction at a radial outside portion; the radial outer surface of the magnetic holder is disposed to contact a radial inner surface of the flange portion of an adjacent claw-like magnetic pole; the magnet holder is formed by bending a non-magnetic plate to have a space to which the permanent magnet is fitted; and two ends of the non-magnetic plate are joined to each other to form the protrusion.
