PURPOSE:To attenuate interference noise between a pole core and a stator, by inserting a spacer formed integrally with a bobbin wound up with the exciting coil of a rotor, between the clicks of the pole core. CONSTITUTION:After the output periphery of a bobbin 20 is wound up with an exciting coil 5, a spacer 30 is bent inside a hinge section 22 and is inserted into a pole core 1. The click 1-p of the pole core 1 is fitted on the concave section 30-a of the spacer 30. Then, a concave section 30-d is formed at the adjacent containing section 30-c of the spacer 30. After that, the click 1-p' of a pole core 1' is fitted on the concave section 30-d. Then, between the clicks 1-p, 1-p' of the pole core 1, 1', the curved surface sections 30-b are arranged, and so the outer peripheries of the clicks 1-p, 1-p' of the pole core 1, 1' and the curved surface sections 30-b of the spacer 30 are formed in a cylindrical shape without rugged sections. |
