Abstract
A plurality of projections are provided abutted with an outer circumference of a columnar axis inserted to an inner circumference of a rotor. The projections are provided in the direction of a magnetic pole in the rotor. When the rotor is fixed to the columnar axis, the projection parts are fixed by 'plunge-in' and the other rotor inner circumference parts have an uniform clearance to the columnar axis. The clearance is filled with an adhesive agent, thereby fixing the rotor to the columnar axis.
