PROBLEM TO BE SOLVED: To automatize the operation of bonding magnetic steel pieces to be inside surface of a rotor yoke for enhanced efficiency and bonding position accuracy in a rotor for an outer rotor-type multipolar generator. SOLUTION: A fixing jig 36 is so designed that the arms 37 of the fixing jig are movable in the direction of the radius of a rotor yoke 25, and a holder 38 is placed at the outer end of each arm. The holders are respectively provided with an opposing plate 46 installed at the outer end of each arm, a plate spring 54 in elastic contact with one side of the magnetic steel piece 26, and a side arresting wall 48 which arrests the position of the other side. Each of the magnetic steel pieces is clamped between the respective plate spring and arresting wall, and the corresponding arm is coaxially inserted into the rotor yoke with an adhesive applied to its inside surface with their relative position kept constant in the axial direction. Then the arms are moved outward in the direction of the radius of the rotor yoke, and thereby the magnetic steel pieces are pressed against the inside surface of the rotor yoke. After drying, the arms are moved inwardly, in the radial direction of the rotor yoke.
