PROBLEM TO BE SOLVED: To provide a rotor and a permanent magnet motor, capable of reducing assembling man hour of the rotor while preventing demagnetization of the permanent magnet.SOLUTION: A rotor 1 includes: a shaft 2; a buffer member 3 integrally formed around the shaft 2; and a cylindrical permanent magnet part 4 disposed on an outer circumferential side of the buffer member 3. The buffer member 3 is inserted in an internal circumference side of the permanent magnet part 4 together with the shaft 2. A permanent magnet motor M includes: the rotor 1; and a stator 6 disposed on an outer circumferential side of the rotor 1 so as to face at a constant interval. |
