ABSTRACT:
A rotor 2 comprises of a pair of claw shape magnetic poles 3N and 3S and plural permanent magnets 5. The permanent magnet 5 is arranged between claw portions of the claw shape magnetic poles 3N and 3S. A permanent magnet fly-out prevention member 61 is arranged at an outer periphery of the claw shape magnetic poles 3N and 3S and prevents the fly-out of the permanent magnet 5 when the rotor 2 rotates. A permanent magnet holding member 62 holds the permanent magnet 5 from an inner periphery side. In a construction in which the permanent magnet fly-out prevention member 61 is arranged between the claw portions of the claw shape magnetic poles 3N and 3S, the working operation for arranging the permanent magnet 5 between the claw portions of the claw shape magnetic poles 3N and 3S can be improved, thereby a vehicle use AC generator having an improved electric power generation efficiency can be provided.
