PURPOSE: To facilitate processing for centering, and to enable prevention of deviation occurring in the center between two shafts during assembly, by a method wherein the front shaft part and the rear shaft part, which emerge from both sides with a rotor positioned therebetween, of a rotor shaft are formed integrally with each other.
CONSTITUTION: A rotor shaft 32 is located in the direction of the axis of a rotor 26, and the rotor shaft 32 is constituted such that a front shaft part 36 which protrudes toward the one side from a bottom part 34 of the rotor 26, and a rear shaft part 40 which is connected to the front shaft part 36 to pass through the rotor 26 and protrudes toward the other side of the rotor 26 through a shaft hole 38 formed in a reinforcing plate 28, are formed in a single coaxial shaft. This constitution facilitates processing for centering, eliminates the risk of deviation in the center occurring between the two shaft parts during assembly, and enables the rotor shaft 32 to be formed integrally with the rotor 26, resulting in ability to prevent accumulation of a size error therebetween.
