PROBLEM TO BE SOLVED: To provide the rotor structure of a rotary electric machine in which strength of the rotor against centrifugal force and attraction force is enhanced, and output torque is increased by reducing leakage flux furthermore. SOLUTION: Leakage flux of permanent magnets 3a and 3b is intercepted by providing a space 6 to extend over the ends 5 and 5 of two adjoining permanent magnets 3a and 3b. A pawl 7 for restricting radial movement of the yoke 4 of a rotor core 2 held between the permanent magnets 3a and 3b is provided in a part of the yoke 4 contiguous to the space 6.
