PURPOSE:To eliminate the production of a magnetic noise at a rotary detector and to facilitate the manufacture of a motor by composing by a metal material bonding method due to a pressure contacting process a rotor shaft of two section of nonmagnetic material and metal material having free machinability. CONSTITUTION:A DC brake unit 10 and a motor 12 are formed on a common shaft 14. A rotor 16 of the motor 12 is mounted on a shaft part 14a, and the unit 10 is mounted on the shaft part 14b. The shaft part 14a is formed of a metal material having free machinability, the shaft part 14b is formed on a nonmagnetic material, and both parts 14a, 14b are swaged under pressure by a friction pressure contacting method. |
