PURPOSE:To reduce a longitudinal play, by a method wherein a coil is fixed to a fixed iron core by clamping the fixed iron core with abutting and retaining claws and fixedly contacting the coil with a holding piece. CONSTITUTION:Outside retaining pieces 14 of a substantially ?-shaped coil holding plate 8 made of a resilient non-magnetic material, abutting pieces 13 and retaining pieces 14 are provided separated from each other with a distance slightly larger than the lamination thickness of a fixed iron core 1. A holding piece 15 is projected from the inside of a central piece 12. The holding plate 8 is attached to end surfaces of the coil 2. The iron core 1 is clamped by the abutting and retaining claws 13 and 14, while the coil 2 is fixedly contacted by the holding piece 15. As a result, the coil 2 is easily fixed to the iron core 1, and the longitudinal play is largely reduced. |
