PROBLEM TO BE SOLVED: To inexpensively manufacture a compressor capable of enduring a rotational torque by affixing a rotor and a rotary shaft in a manner not to demagnetize a permanent magnet, because a cylindrical rotary shaft provided with a notch part at one axial part is fitted and fixed with a rotor having an inside diameter shape similar to a shape of the rotary shaft with the notch part. SOLUTION: A motor is equipped with a rotor having a permanent magnet using a ferrite magnet. A cylindrical rotary shaft provided with a notch at one axial part is fitted and fixed with a rotor having an inside diameter shape similar to a shape of the rotary shaft with the notch part.
