<P>PROBLEM TO BE SOLVED: To prevent deformation due to a centrifugal force acting to a plurality of magnetic members by improving the rigidity of a cylindrical rotor of a rotating electric machine when the magnetic members are supported on the outer circumferential surface of the rotor. Ž<P>SOLUTION: An outer rotor 13 of an electric motor M is configured so that a plurality of coupling members 33 disposed with a predetermined interval in a circumferential direction couple between a center ring 31 and rotor flanges 32L, 32R which are spaced and fixed in an axial line L direction in rotating shaft 34, 36, and induction magnetic poles 38L, 38R are supported between two adjacent coupling members 33. With this configuration, the coupling members 33 can improve the rigidity of the outer rotor 13, thereby enabling to prevent the deformation of the outer rotor 13 due to a centrifugal force acting to the induction magnetic poles 38L, 38R. In addition, the induction magnetic poles 38L, 38R are pressed on the center ring 31 by an elastic member 41 disposed between the rotor flanges 32L, 32R, the variation in dimension in an axial line L direction between the induction magnetic poles 38L, 38R can be absorbed to prevent the generation of backlash.
