PURPOSE:To eliminate the variation in the vibration sound or an air gap due to the irregular damage of an armature winding by extending the collar of a bobbin. CONSTITUTION:A stator 1 of substantially U-shape has parallel magnetic path pieces 2a, 2b, and poles 3c, 3d are formed inside the open end. A bobbin 8, on which an armature winding 9 is wound, is mounted on the piece 2a. Contacts 13a, 13b are respectively formed at the collars 12a, 12b of the bobbin 11, and contacted or pressure-contacted with the inner surface of the piece 2b. In this manner, the damage of the armature winding can be eliminated, and the vibration sound due to the fluctuation or the air gap can be obviated. |
