PROBLEM TO BE SOLVED: To permit thermal expansion of a rotor body, a permanent magnet, and adhesive, thereby preventing the permanent magnet from being cracked by a difference between thermal expansion coefficients of the rotor body, the permanent magnet, and the adhesive. SOLUTION: This rotor with the permanent magnet is structured by fitting the cylindrical permanent magnet 12 onto the fitting surface 15 (outer periphery) of a rotor body 11 with the adhesive. To a section where the adhesive 13... is applied to the rotor body 11, its symmetrical section is kept unapplied with regard to a rotor shaft. COPYRIGHT: (C)2003,JPO
