PURPOSE:To contrive mass production of magnet rotors, by surrounding the entire face of a cylindrical magnet with a double cylindrical member and fitting the inner circumference of the cylindrical member to a shaft. CONSTITUTION:A cylindrical magnet 3 is pressure inserted through adhesive between outer and inner cylindrical members 5, 6 of double cylindrical members 4a, 4b, so as to provide a magnet member. Then the magnet member is fitted to a shaft 1 so as to provide a magnet rotor. Since the magnet member is assembled first then fitted to the shaft 1, process is simplified and automatic assembling can be carried out through a robot. Furthermore, since axis is defined by double cylindrical members 4a, 4b, unbalance of rotor is suppressed, resulting in an inexpensive magnet rotor which is suitable for high speed rotation and can be mass produced.
