PURPOSE:To eliminate the deflection of a pole by forming two or more separate pole units, then engaging and press-fitting a control plate to the pole, thereby rigidly coupling the separate pole units and reinforcing the pole. CONSTITUTION:Two separate pole units 13 are disposed oppositely to a pole 11, the both ends of the pole units 13 are formed to becomes a surface parallel with a stator, and a control plate 20 made of nonmagnetic material formed with a hole 19 to be engaged with the pole 11 of the pole unit 13 is press-fitted. Then, axles 17, 18 provided with wheels 16 are placed on the ends of the pole units 13, 13. Then, the control plate 21 is press-fitted to the pole unit 13. The pole unit 13 is rigidly coupled by the plate 21, and the axles 17, 18 are secured to the pole unit 13 by the bent portions 21A at both ends of the plate 21. |
