PURPOSE:To prevent a noise caused by a bearing end from occurring and to minimize the wears of parts by positioning and securing a rotor in a shaft direction by utilizing the magnetic attraction of a stator and the rotor. CONSTITUTION:A rotor 11 is positioned and secured in the direction of a shaft 5 by utilizing the magnetic attraction between a stator 13 and the rotor 11. The magnetically attracting force between the stator 13 and the rotor 11 has a sufficiently large magnitude to position the rotor 11 in the direction of the shaft 5, and the shaft 5 is supported only by the inner periphery of a sleeve bearing 4. |
