PROBLEM TO BE SOLVED: To provide a rotor structure of a permanent magnet rotating electric machine, which is enhanced in the transmission property of rotation torque, can suppress the occurrence of eddy current loss, and is high in productivity by means of a practical production method, while the permanent magnet serves as the interference of a reinforcing ring to endure high speed rotation. SOLUTION: In the rotor structure of the permanent magnet rotating electric machine, cylindrically formed permanent magnets 3 are disposed on the outer circumference of a rotor shaft 2 to transmit the torque working on the permanent magnets 3 to the rotary shaft 2. The rotor structure includes a cylindrical reinforcing ring 5 provided on the outer circumference of the permanent magnets 3 so as to project both ends of the permanent magnets 3, and a side surface member 4 formed into a bottomed cylindrical shape and having a portion projecting from the reinforcing ring 5 of the permanent magnet 3 being fit into the cylindrical portion 4a and also having the rotary shaft 2 being fit into the shaft hole 4c formed at the bottom 4b.
